Bob,
I got enough of a run to the motorway to heat the engine before opening it up and initial feel was fierce, I actually spun the wheels with kick down it at 90mph, that is just incredible. Now I have the car performance that I was after when I bought the 63! Keeping my eyes peeled on the motorway for anyone brave enough to have a go.. ;)
Thanks,

Tomas,
Everyone at the shop is more than pleased with the end result of everything done to the car. I just wanted to say thank you for all of the support through this. The car is very smooth and powerful throughout all of its gears and drives just like it should. I'm certain that the customer will be very pleased.
Thanks again,

OH HELL YEAH!
Definitely more pull and revs are higher between shifts....I need something to throw down on to feel the difference better. Think I will troll for Mustangs and Camaros this evening and work my up to the exotics.....LOL
BIG Thanks Leon!

Dear Leon,
I recently ordered your C74 aero package and installed it successfully on my 2010 C63 AMG. The result is nothing short of spectacular, and I am extremely pleased! I want to thank you and your company for producing a superb product.

Bob,
Just installed the intercooler pump and carbon fiber air box. I was more than pleased to see a noticeable jump in power and throttle response. It has been my experience that on engines of around 500hp you are going to have to have an increase of at least 25-30hp to notice any difference. I am very happy with the results. Thanks for your help.
Best regards,

Leon,
I just wanted to thank you and the team at RENNtech for the incredible job done on my 07 SL600. The package 3 along with the limited slip differential and the sport mufflers have taken this from a great car to a sleeping monster. Through the TCU upgrade I now have complete control over transmission in manual as in the AMG version which was not available before. The exhaust note is so incredible, popping when decelerating beautiful when cruising and unbelievable awesome when the hammer goes down. I couldn't be happier with the car. Even with all of the new found power I can still get 18 miles to the gallon around town. And best of all my 14 year old son loves it. He can't wait to go for rides.
Thank you again.

Took 'er out on 95 the other day-and wow! Exactly what I wanted. When you jump on it at speed, like 70 or so and hammer it, the exhaust becomes glorious and sounds like Parnelli Jones in his ‘69 Boss Trans-am car. #15 in your program.
Please tell Harmut it’s perfect and was just what I wanted on the highway. Thank you guys.

"We use Renntech to build ours because, quite frankly, we don't think there's anyone else out there who knows that box as well as they do. We've put close to 700 AWHP and nearly identical TQ through the upgraded box and they've performed flawlessly."

I have 2008 C63 which I bought May of 2008. I was one of the first few to own C63 in Canada. For the first 2 and a half years I had it stock and was quite satisfied with the power but as time went on the urge to see the true potential of this car over came me and I got the tune.
I went through the same dilemma as you on what tune to get, but I settled with Renntech basically because their very reputable company with a quality product. That being said the Renntech tune is one of the more expensive tunes. However now that I have been driving it for a few days it was worth it. The car pulls so hard its ridiculous. C mode now with the tune feels like S mode stock and S mode tuned.......out of this world!
I specifically asked for a 93 octane tune which renntech informed me was generally what they do with their tunes. We have 94 octane gas up here in Calgary Canada at our Husky stations so I believe it helps. Renntech claims 517hp and 485Ft/lbs from crank on their website but I think this is conservative. I hope can find a dyno and see what power Im truly putting down. Any way its worth it whatever tune you get but for me Renntech was the best choice because it gave me peace of mind that they do great job and my engine wont blow up.
