We are about to install the first one on a customers car, we will post pics and info on the install and the results in the next week but I just wanted to post here and see if anyone else had done it and what they thought.

Branden, make sure you also post pre and post dyno's as well. :thumbup:
damn - I need to get one of our customers on the dyno :\. We've done 3 x CLS63s and 2 x E63s. I'm all in for a comparo though.
I have never seen good gains on any '06 55K car built in '06. Let us know. I will be getting full Renntaech upgrade asap.
