I too will be getting the MHP long tube headers and tune in the next week or so. I opted to add high flow cats (300cpi) for an additional $500 I believe, however there are no secondary cats with this system. As has been posted before, this system will bolt on from the engine all the way to the resonator which makes this setup even more appealing to me! Originally I thought for sure there was going to be some cutting/welding, but this is not the case and I love the fact that I can go back to stock if I ever needed to!

Anyhow, I will be sure to keep everyone posted on my results. I may or may not dyno tune, however I will definitely provide track (drag strip) results which are more important to me anyway. I'm not the greatest launcher compared to mthis or Dads_C63, who both seem to get great numbers, but I'm still hoping for a huge improvement compared to last fall where I did some base runs. Just for reference, I got in 3 runs last fall and achieved the following times:

- 60' was consistently 2.3xx on all 3 runs.
I was running on fairly new Bridgestone RE050A PP tires, 265/19, inflated to 38-40psi. I will lower the pressure to roughly 30psi and see if that improves my 60' times. Also I now have coilovers which I've noticed help a bit with weight transfer. Hopefully I can get closer to 2.000 60' times, if not better!

My times ranged from 13.1-13.3 @ 110-111 mph...bad I know. With a decent launch I expect I could knock those numbers down around the 12.6 range stock.

In anycase, even with a similar launch, I'm hoping the new headers and tune can get me closer to 12 flat. I know mthis and Dads_C63 are expecting much better numbers, mid 11s I assume. With practice I'm hoping for those kinda numbers too, but if I can knock off over 1 sec from my base times I'll be very happy. From there I'll improve my technique to achieve the best times possible.

The numbers that should improve regardless of launch are my trap times. Again, I'm hoping for at least 120mph trap which I don't think is unreasonable given the output of this setup. On paper this package should do more, but I was also expecting around 113 trap on my base runs so we shall see.

In anycase I'm excited for the summer season! Also, I think there have been some false numbers floating around regarding the pricing on this package. I know for this initial introductory batch (I think 10 sets) the package price for the LTs, mids and ECU/TCU V2 tune is $7645, $500 less if you go without cats. I think I read some posts where people were saying roughly $6000 for the ECU/TCU alone. It may have been that price at one time, but all I know is right now they are offering this package for the above listed price.

The idea of sending him 7k of my hard earned money boggles the mind. Has anyone ever realized that MHP has zero claims for anything other than a C63? They have a website full of claims for tuning and power but all they quote is that their other project of a C63 was able to go really quick.

So lets see. If he were so great might he have actual claims for power increases on things like M5's and 997's?

In a world where RENNtech is cheaper and just as quick, where Kleemann has become a 1/2 priced tuner (they are priced right in the market now and not expensive at all), why do you want to rick a company that has a very spotty and very short history.

mthis

oh man you ganna have a biger blast. you getting ecu and header at same time mint good luck.

mthis

i think track numbers will speak soon and you will see what MHP Kleeman and renntech MKb are all about. as far as i know dadc63 is testing MKB to MHP some one else is testing Kleeman to MHP and im might just go up against a renntech c63 so we will find out whos the beter tuner for our c63

7K for headers and a tune is just plain

ANY reputable header shop will buld you one offs for 2K and laugh all the way to the bank. And his tunes, well I will just leave that one alone.

Good luck Nrgy. I hope you get the results you are paying for and deserve.

See yeah

Exciting news, nrgy! Look forward to seeing your results - keep us posted.

Track times do speak volumes... can't wait to see what the C63 record is by this fall.

Dads C63

nrgy,
You are going to have a blast and love driving/racing your car. They really do come alive! Good luck and keep us informed.

For those of you that are always comparing the dollars to different tunes makes me chuckle. The old saying "you get what you pay for" is so true in car racing. There will always be a cheaper set of headers, cheaper tune, and cheaper parts as a general rule. If you want to be "average" then keep that mind set. If you want to race and win then you will have to step up the game. I have been through years of racing and quality speaks for itself. Build an economy motor and see how long it lasts. Build a quality motor like AMG and see how long it lasts. I purchased the MKB package originally because they are a quality house and have a great reputation in Germany. Guess what, their package is the most expensive but yields the best results for their stage package. Renntech and Kleeman both have quality parts and tunes. MHP is doing a ton of R&D on the C63 with their in house car so who cares what other brands they can brag about. I don't get that comment? If you want a BMW or Porshce tune then go to a BMW or Porsche specialist. MHP may offer great tunes for the BMW and Porsche for all I know but he's in the MB world here. Buy the lower priced tunes and headers but don't complain when you can't keep up at the track. Thats just stating facts. You will ALWAYS pay for quality in car racing. Step up and pay for the R&D on these cars. For goodness sake, we own an AMG Mercedes and you shouldn't be putting 2,000 headers on a MB. Lets go racing and break some records in the fall. Be safe!

God Bless,
Keith

I am getting MHP LTs in the first sets also. Anybody install it faster then me please coment on how easy/hard the install is!

MRAMG1

Oh well good luck guys, and I hope you get what you are defintily paying for.

See yeah

Dads C63

MRAMG1,
You have some valid points but the results speak for themselves. So far the quality products are producing the best results. No sucker born here. Lets go racing!

MRAMG1

I wish you all good luck with WHOMEVER you choose to buy from guys, and I REALLY do hope you get what you pay for.

See yeah at the track

DaGS1800

I agree with Dads C63... Although MRAMG1 brings up some valid points, I have had some terrible experiences in the past trying to cut corners...and I ended up paying even more than I would have in the first place trying to make up for my mistakes... MRAMG1’s point of view can def be correct when you are talking about hardware made of the same material and so on, but as far as the ECU tunes are concerned this is software technology which isn’t always equal. There are already results which favor Dads C63's view, however numbers don’t always mean everything, so I am curious to see tune vs. tune on a track/street.

NRGY, don’t forget to post some results! Your car is going to be like day and night when you get it back

nrgy

Haha, yeah that was one of the reasons I haven't done just an ECU tune yet. I've been waiting for long tubes all along just so I get a huge kick in the pants when I do both at the same time. I know butt dynos aren't very accurate, but hopefully these two mods will send this butt dyno off the charts

In regards to my decision to go with MHP, I've been watching the development of performance products for the C63 since day 1. I have not done business with any of the MB tuning companies in the past, and at the end of the day I simply feel more comfortable going with a company that has shown actual results at the drag strip with the C63. This isn't a knock on the other tuners, but since the C63 is fairly new we still don't have the years of data/results like the E55 for example, showing all the various tuners. We do, however, have real world results of MHP's C63 and this gives me some idea of what to expect.

I was also impressed with Dads_C63 MKB numbers, and even thought about dishing out the big bucks for that package, simply because their results have been proven by another member. But for what I think is $15k for shorties and a tune, $7k doesn't seem that bad for LTs and a tune.

But in any case we should have a lot of data flowing in from several sources over the next several months which should help out the community, good or bad.

mkonei

too much BS is attached to the MHP name. i hope everyone is doing some reading before they cough up 7000.

SE7ENC55

When do u guys think youll have results? did you guys get the package yet? mthis should have his by now i think no?

nrgy

Last I heard it will still be a couple weeks yet. I assume mthis and Dad_C63 have been in closer contact with MHP so they may be getting theirs first. I just hope I can get them in my hands and on the car before June starts!

And like I said in a previous reply, I have been following MHP ever since he joined these boards. I haven't dug up any BS in regards to his C63 tuning, which is the only tuning that concerns me at this point. I'm not trying to be a fanboy, but I honestly have not found one complaint with his C63 tuning? The fact that MHP owns a C63 that he has access to 24/7 gives me even more confidence that the headers/mids will bolt on without problems, and the tune has been optimally tweaked to the new configuration.

groupB

Start looking at these prices http://renntechmercedes.com/c.html (page 3) and 7k for a tune and headers seems pretty reasonable! That's $8290 for ECU and SHORT headers!

CRAZYC63

any update on this yet?

I'm really considering going this route and would like to know how the MHP tune and headers have worked out. Especially with the shift-time improvement.

Thanks

Mike

I do have an update actually. While I'm still waiting on the headers, which I have been told will be a matter of days before they ship, I did end up getting the V3 ECU/TCU tune last week. Let me just say the turnaround was very fast. I overnighted my ECU Monday afternoon and got it back Thursday morning, just in time for a very big car cruise last Saturday.

I have roughly 300 mi on the new tune, and still breaking it in. I really wanted to wait to give my impressions until after I recoreded some 1/4 mi times, however due to scheduling issues it could take a month or more before I can make some runs So I'll just give my impressions so far.

I'll try to avoid giving my butt dyno impressions as much as I can as I realize there is often a placebo effect when it comes to power adders, but I'll just say the car felt very strong. During my drive Saturday I was crusing along around 60 mph, ESP on and in M mode, and I downshifted into 3rd and floored it. My ESP light immediately began flashing as the tires started spinning and the rear wiggled as the tires broke loose...@ 60 mph straight and level, dry pavement. I really don't remember being able to do this before when stock, can anyone else confirm? If you keep the revs above 2800 rpm, which as Andy says is where all our torque is available, everytime you hit the gas you'll get that kick in the butt feel. I did just that and it definately gave that sensation of getting slammed in the back.

During launches the front end seems to get lighter than before as well. Perhaps this is a combination of the coilovers I'm running and the added power. I will say though, I have been able to hook up pretty well with this setup as long as I roll into the throttle nice and easy at first, and then let er rip. The weight transfer seems to keep weight on the rear to minimize tire spin.

Like I said before, I'm really anxious to get the car to the track. I could go on all day about how great the tune feels but it really doesn't help anyone out without solid numbers. But I would be shocked if my 1/4 mi times didn't improve GREATLY based on my impressions so far. But by the time I get to the track I'll probably have headers as well.

CRAZYC63

nrgy,

Have you noticed quicker shift times or any difference at all with the TCU part of the tune compared to stock? If so, what did you notice?

Thanks!

Mike
