Not sure about the NA guys but the SLK32, C32, and E55 guys seem to have good luck with cams without the ECU being reprogrammed for them. Granted everyone that is running cams seems to be running an updated ECU but it is the program that comes with the stage 1 package (ECU & Pulley).
I am sure they could get better results with additional programming but they are seeing decent results from just dropping in the cams.
The E55 guys are the ones running larger TB's and again seem to have good results without reprogramming.
Terrific. So that pertains to what aspect of the NA Crossfire ? So, who did the cams, who did the updated ECU ? Dude your posts leave alot to be desired !!! Why are you discussing the MB E55 ? And why do you just say "these guys are doing this" ... without providing information on who, what where !!!
