Welcome RENNtech!

Easily one of the best MB tuners in the country. They had done several cars for me and the performance gains have been over the top.

Quick story: about 2 years ago I had a problem with my MB 600 after getting a performance upgrade (620hp) from RENNtech. It wouldn't go over 160-165mph for more than 5-10 seconds without going into limp mode. It was diagnosed that the IC's were getting heat soaked so fast and that was causing the problem. It was something they had seen before.

RENNtech installed their own IC's, retuned the car, ran it on their dyno up to 192mph (I took a picture of that) for a minute or so to show me that it wouldn't go into limp mode and it hasn't caused me a problem since. The car has been rock steady as was my RENNtech tuned super-charged E55.

If you have an MB you have to talk with RENNtech.

 

Welcome guys!

At ACG we have a long-standing relationship with RENNtech. We are able to do RENNtech software ECU flashes in-house. This assures that there is no down-time associated with shipping your ECU to RENNtech facilities to get flashed.

RENNtech is easily the best Mercedes Benz tuner in the USA. When it comes to safety, top power and the top customer/installer support, RENNtech is the top dog.
