Not sure if this has already been posted by someone else but figured some might be interested.
I sent an email to Kleemann USA over the weekend to inquire about C63 performance upgardes and this what they replied:

Hello Dan-
Thank you for contacting KLEEMANN USA!
We currently have ECU programming and headers available for your C63 AMG.
ECU programming is priced at $1495.00. This upgrade has recently been shown to provide gains of 50-55 rear wheel HP- bringing C63 engine output closer to that of the SL63. The ECU must be removed from the vehicle and sent to our USA headquarters for programming. I can typically program and ship the ECU back to you the same day I receive it.
KLEEMANN is also offer a Header, down pipe and catalyst combination which will provide gains of 35 HP. When the headers are combined with ECU programming, we are seeing gains of 90 HP. Headers are priced at $3995.00.
If you have any other questions or concerns, please don't hesitate contacting me and thank you again for your interest in our line of tuning solutions for your Mercedes-Benz!

Thanks for posting. The HP gains sound pretty impressive. The pricing still seems a little expensive, but not as crazy as Renntech.

I would love to do this, but I'm just afraid that I will void my car's warranty for a few extra horses. Not sure if it's worth it.

Hi Shaker,

Keep us updated if you choose to do the ECU tunning. Since E63PWR has done it, we need one more vehicle to verify the data.

Very good question regarding the warranty. Park Place Motors, where I bought the car is also a Kleemann sales outlet, and they said that there would not be any issue with voided warranty as Kleemann and or Park Place would cover. Kleemann also works very closely with many MB dealerships.

That's $5,500 for 90hp.

I'm going to VRP next week and for $4,800 I'm getting 130 more hp. VR530, Headers, and Tune. 570 flywheel horsepower or about 470rwhp.

Will have done next Monday and Tuesday...

Please post before and after dyno.

OverBudget

I will.

Just curious, but do you have new information that hasn't been released yet from VRP? I've been trying to stay up to date on their developement progress for the 6.2 engine and VR570 package, but have not read anything new for a month or so, but I havn't been in direct contact with them either.

Also, I asked VRP before and they were unable to give me an answer at the time, but the VR530 and VR570 packages were based off the 6.2 engine producing 500 hp, not our detuned 450hp version. So are they bringing our engine back to 500 hp, THEN adding the tunes?

Appreciate any knowledge you can share.

shaker

I look at differently, it's ONLY $1495 for 55 RWHP... I am also going to ask Vadim for some information as I have just also installed the new VRP air filters and was very impressed with their service.Will VRP back up the MB warranty as well?

OverBudget

I don't think I'm sharing anything I'm not supposed to...

I've been in personal contact with Vadim at VRP for about 2 months. I think my C63 is the first to get VR570 next week.

They aren't taking it to some level and then tweaking it. They have researched and understand how the C63 is limited and with the VR530 items + the headers + the tune they can do based upon what they have learned, I am told I will have 570 flywheel horsepower.

I'm sure they will start posting stuff once they complete my car...

Warranty issues are dealer specific. I have contacted the local dealer I will use and he would not comment specifically on certain mods. Renntech locally says that MB locally will stand by warranty issues on Renntech installed items. I've read about the Magnasson Moss warranty act. Dealers can fight you and make you go the legal route, but technically they cannot void any warranty unless they SPECIFICALLY can prove that your mod caused a certain problem...

Thanks for sharing. I knew another member on here had taken his car into VRP to do a baseline dyno about a month ago, and VRP hinted that they knew how the engine was detuned, but like I said that was the last I heard on any developement for the C63.

Sounds like you will be the pioneer! Very excited and looking forward to the results.

porschelover1

please if possible post a video with side by side with C63 VRP vs C63 STOCK for to see the difference between the cars and will be future VRP´s customer!!!

I guess I could see the 50-55hp gain from the ECU tune (if it truely is that detuned from the factory)...Im anxiously waiting to see the results from VRP's modifications.

OverBudget

Go to www.vrptuning.com and look for VR530. It involves filters, pulleys, heat spacers, thermostat.

No one has told me how much power the tune gives vs. how much the headers give vs. the other items (VR530). I'm guessing about 55hp on the tune, 25hp on the headers (and I'm also getting the secondary CAT's removed), and 50hp from the VR530. Ala carte, VR530 is $1,000 installed, the headers are about $2,000 (plus installation), so the tune is around $1,500 or so.

xandi911

THE FIRST who really SHOWS me the REAL GAIN, against a stock C63 vs a MODDED C63(no matter, KLEEMANN,VRP,.....) in video from a ROLL.....

After that ill be the new costumer from this TUNER....

im tired of dealers that promess lots of GAINS, and in REAL LIFE you have a stock CAR, with no more warranty.

im looking for the tune, i just wanna to choose the BEST!

shaker

Can we use your C63 as the stock car for the purposes of your required video??
You contradict yourself in your post. You first say that you will be the customer of the tuner who can first demonstrate the real gain (you don't say how much gain) and then you want the best and no mention of price....hhhhmmmm
So everyone else will test to help you choose.... I don't think so.... where is your skin in the game then?

xandi911

so i will explain again...

DYNO tests IMO DONT SHOW NOTHING....

REAL LIFE IS REAL LIFE...

IF someone that did a ECU TUNE test against other STOCK C63, and prove that this MODE really worth it. SO i will buy it...

really worth it= a difference from a roll 40mph~150mph of 2,3 cars LENGHT at MINIMUM.

got it?

shaker

so you agree that you will be the slow guy in the video then???

xandi911

if this was a joke sorry i didnt got it...

bad english

OverBudget

xandi911: I will have the work done next Monday and Tuesday. All of the stock C63's are dyno'ing out at around 374 rear wheel horsepower. VRP is going to dyno the car when the mods are done. I expect about 475 rear wheel horsepower.

If that doesn't satisfy you, then too bad. I'm not going out on the highway, finding another idiot willing to street race, potentially lose our license, and have a 3rd guy video tape our illegal activities.

Dyno = better measure of improvement than video.

shaker

xandi911

OK the car is yours you do what you wanna do

NORTH 44 C63

Some how,,,,,,You remind me of an ambulance chaser.......

shaker

Very well put.... what an idiot xandi911 is... has so many comments to make and in pretty good english, I might add, but then when it comes to putting money in the game all he wants to hear is the end results and via video no doubt.... so that he can make his decision.....what a loser!

I actually think some objective evidence of a real world performance gain isn't an unreasonable expectation before parting with $5,500. I'm certainly no dyno expert, but my understanding is that dyno results can be manipulated. Drag strip results showing a higher terminal velocity and/or a lower ET or video showing better roll on performance is pretty convincing evidence. The porsche tuners and enthusiasts have typically provided this kind of information. Ronald Reagan was right when he said trust but verify. My $.02 fwiw.
