Good morning Mitchell,

I spent quite a bit of time in the car this weekend and I thought I would share a few impressions. I like the exhaust note from the mufflers as it is just what I was looking for. Deep tone, not too loud, lets you know it’s there without being overbearing. Along with the air filters I can tell the car “breathes” much better.
I am quite impressed with the increase in performance. My right foot is still being re-trained as having driven the car for 8 months now, my right foot had become accustomed to pressing down certain amounts for different effects.
Now, I have no aspirations to race or take the car out to a track and I don’t care that much about Dyno values (except for maybe bragging rights). What I do care about is how the car has become more fun to drive and that’s the bottom line.
Mercedes made this Mille Miglia edition with aesthetic additions and for the life of me I couldn’t understand why they didn’t add some performance upgrades as well. I now feel RennTech has enabled this car to be the car it should have been all along.
I am thinking that maybe mounting the RennTech badges I might gain another 10 HP?
Thanks for taking the time to answer all my questions and being extremely vigilant and helpful through the process.

Best regards,

Steve Pummill

Mark S,

Thank you again for your help with my ECU tune. Pulled the ECU on Monday and had it installed by noon on Wednesday! The engine is now a true beast!! Could not ask for a better experience.

All the best,

Blair

John,

I wanted to follow up with you in regards to the tune you guys performed on the S63AMG on Feb. 4th!

Simply Amazing!

The car does triple digits without even trying. I find myself constantly cruising at 93mph and feels as if I'm doing 65mph

Thanks again, John

Mark,

Happy Thanksgiving to you and the family. I would like to express my extreme satisfaction at the quality of customer service you extended me with my CLA 45 project (turbo upgrade with diverter valve, ECU upgrade, and downpipe). Renntech might have just hit a home run with this car. This car has become a whole new machine. It begs to be pushed and I know I will oblige as I enjoy this further. I will certainly recommend any of this upgrade to my fellow ’45 owners. The price of admission is reasonable especially for a reputable outfit like Renntech. I look forward to possible new upgrades to make an excellent car superlative in every aspect. Thank you very much!

Mark S,

Thanks for your help in my decision to chip the CLS 550. I just picked up the car Friday. It was a great car to begin with, but the ECU upgrade has taken it to another level. Your complete knowledge of the upgrade process made my decision much easier. The ECU performs EXACTLY as you described. All i can say is WOW!

Thanks again,
Jim

Morning Mark S.

Just a little note to let you know the kit is installed and it has transferred the car into a Beast!

What is fantastic is that it is very smooth and comfortable while driving around but when you put your foot down it comes to life.

I will put in some race fuel on the weekend and really open her up.

Can you tell me what are the rated hp and tq figures I should be at now? I know without down pipe was 460 but it feels like more so was wondering.

Thanks again for all your help and the great service you and RENNtech have given me.


Regards,

Adam Morton-Gittens

Joe,

WOW what a difference. I should have NOT waited this long to do this upgrade. It seems to me that she shifting is way better-there used to be a lag between when the turbos would spool up after you pressed on the gas-now it's way smoother. Thanks again for money well spent!

Hi Joe,

Thanks for following up with me. I installed the software the other day and it is AMAZING! I could not be happier with the speed of delivery, assistance and help you deliver. And the product delivers as promised.

I plan to install the air filters this evening.

I was wondering if you ever put the LSD’s on sale? I want to be able to deliver my new found torque to the ground safely. I also see myself purchasing the TCU in the near future as well.

You guys rock and I will be sure to write a nice entry on your site soon. Thanks so much for all the help.
