ECU Tune
Anyone have experience with an ECU piggy back that puts out most power without having to install aftermarket downpipe..plug and play. Renntech, Rebellion...??

Don't know if if got the answers you needed already, but if not I have recent experience having my 03 SL55 ECU tuned by PresserTec. My only mod is 77mm S/C pulley. I haven't put it on the dyno, however the car is crazy fast. The HP increase, according to PresserTec after tuning is roughly 550HP, 604TQ. I won't know til it's dynoed, but it sure feels powerful.
