RENNTECH ECU/TCU Upgrade
Hello,
Have a 05 CL65 with 9K on it. Looking to do the HP upgrade from Renntech with the ECU and TCU upgrade.
I would like to know if anybody has done this and if they experienced any problems after it was installed and if they really noticed the increase in HP from 612hp to 670hp... I know these V-12's are a work of art and also very sensitive.
Your comments would be much appreciated.

I have had 2 CL65s and an S65 modified by Renntech. I have had no problems with the modifications. In fact, I driveability improved after the Renntech ECU/TCU modification. Also, the power difference is noticeable. You won't be disappointed.

At least give Marcin @ speed driven a call...do yourself a favor. TRUST me <-----not employed, but a customer for life. ECU&TCU for half the price of competitors... check it out amigo. I'm not saying the others are not good or even great, but at least compare options...They built the fastest mile shootout sl @197.xx mph
