I joined the MHP family
The tune I am getting from them next week is indeed the OE and he mentioned the very same 11rw you did on an E63. Thanks!
Im very excited.
A more probable indication, however, is the current set of data available right now (2 to 3 years after the release of the C63); data that points out that on the track, MHP equipped cars have been doing much better than other cars. Consider this: you've got 5 different cars with 5 different drivers in 5 different conditions all achieving the 11.5 mark @ 122+ mph multiple times. So even though the tracks were different, conditions were different, and even drivers were different, the tune/mods performed very consistently. I'm not saying they don't matter, but I'm saying that is a very strong indication of the strength of the product. Other tuners, who are arguably bigger companies (except RennTech), have sold a LOT more than MHP yet they have still not shown ONE single good pass in 3 years. In fact, things are actually worse: some of those cars did run and showed very poor results on the track despite the incredibly high dyno numbers
It'd be hard to believe that in 3 years, among all the non-MHP C63 cars, not one single decent driver went to the track in semi-decent conditions.EDIT: I am not affiliated with MHP or have even used their products at all, so I'm not a poster boy for them if you were gonna say that
I am only analyzing current data set that has been available for at least 2 years now.

I am only analyzing current data set that has been available for at least 2 years now.My research has been only using dyno sheets and looking at the power band how the gains from each tune. Nothing about MHP's dyno sheets justifies the more expensive tune. As far as track results you would be hard pressed to prove it also. You would need a controlled environment where you know everything about the cars. Same drivers, tires, conditions ect.
I could say the same. How about you show me some tech sheets supporting your claim on how MHP is able to gain better track results when the dyno sheets come back with the same HP/TQ gains on almost every ECU tune on the market. Why does it do better? What do they do different? Trade secret? It sure does cost a hell of a lot more money for an MHP tune. Perceived value maybe?

What makes MHP better? How are they able to achieve better track times while still posting the same dyno numbers as the other competitors.
Other than hype and charging more money for it I still haven't seen any data from the MHP side either.
As far as a show down it would have been cool and put this debate to rest once and for all. On the downside it would have put a few companies out of business as well.

Now with that said, go look around the W211 section and you can find out some information about them.
To everyone involved, good luck. And please do some research before spending your money on ANY tune.

Ohhh jeezzz.. Drama... TheRicker and Jcart.. This cant be good!
Research and due diligence on the part of the consumer is paramount when choosing a tuner.
Has the tuner's dyno claim been backed up with independent dynos?
Has the tuning been track-tested and, if so, what were the results?
Does the tuner test, research, and optimize their tuning on paying customers' vehicles? If so, do you (the potential client) care?
Has the tuner had client motors blow up while running their tuning, and if so, how catastrophic was the damage?
What is the price/performance ratio and is the tuner perceived as a good initial (and long-term) value?
How is the initial and on-going customer service? It's a given that it's good when courting a potential client, but is it still good down the road, and (hopefully never, but unfortunately possibly) in the face of adversity?
What (if any) warranty coverage does the tuner offer? Some tuners offer real warranties to replace lost MB/AMG coverage on the specific parts, others' idea of warranty is offering to put you back to stock before flatbedding the vehicle to the dealer (which likely could be construed as fraud by the individual toward MBUSA, with potentially major fines and/or jailtime).
These (and likely many others) are all important considerations when partnering with a tuner. And you should absolutely search anywhere and everywhere in compiling your data. AFAIK, a replacement engine for a M156 is something ridiculous like $40,000+, plus install. If a catastrophic engine failure occurred on a tuned vehicle, it would actually be worth considering writing the whole thing off as a loss and buying a new C63... crazy as it is to say. Food for thought.
Sorry for the OT, OP: good luck and enjoy your newfound power!

. By the way, one of RennTech's car did the one mile run and has done extremely well.

So be very careful when buying a tune. Don't just go with any company that offers high dyno numbers. Consider the whole package: dyno, track data, high-speed runs, etc....
I have yet seen a tune only from any other tuner in the high 11's with a trap of 118 mph.
The tune speaks for itself.
Renntech is more of a jerk when you ask for a refund. I returned my tune in Oct 2009 and they charged me a 20% restocking fee.
Neither of those companies claimed dyno results were what they should have been except the MHP tune.
I'm the only on this forum and maybe the only on ever to personally test all 3 major tuner players in this field.
I had to dispute the cc charges with Renntech and are still to this day out a few hundred dollars.
Don't believe anyone on the return policy until you actually try to do the return.

Obviously I am happy with my setup although if I had Keith's deep pockets I would get a new tune from Andy. I had the opportunity to track both cars at a private rental but Keith's car had the new heads and a cat back exhaust and his was 2/10’s quicker and 2 mph faster although the margin gets much more difficult when you get well into the 11’s and 122+mph.

What can not be debated is that track results, especially trap speeds, tell much more about real power than any dyno. Don’t bother bringing up elevations, temperature, driver error or any other issue that could hamper optimum results. The truth is we only look at the BEST runs that a car has ever made ( we all have crappy ones once in a while) and the C63’s that have logged the pinnacle et’s and trap speeds during the past two years are from a very small group of tuners and are dominated by MHP products especially with the long tube headers.
Does this mean you shouldn’t by another tuner’s product? Of course not, economics factor into the decision but you should be looking for proven results that will put your car in the performance per dollar ratio that you want to be in.

That is a sweet tune only 1/4, But without the MT's you would be in the 12's just like every other tune ive seen on this forum.
Maybe the top speed run is better on the MHP tune. Ill give ya that, but honestly, I dont care about that. I live my life 1/4 mile a time time.. lol

Ahh a post with some data. Thank you.
I really havent looked into MHP as of yet. I dont even know how much more expensive they are. I do know they cost more though. I also dont think I could get a MHP tune in NY. Is it a west coast thing only?
How much is a MHP tune?
Edit: Never mind I searched the price. $2500. About double the price. I do notice though that they do a TCU tune along with the ECU tune. Couldnt that be where the gains are being seen?
