Has anyone else scanned theirs? I've got a NBS VMAX and I can't find anything I've done to limit the throttle from opening all the way. Went back to a stock tune and the same issue. Wonder if its set that way from the factory..
On another note after playing with the E38 ECM all I can say is GM went a bit over board with all the spark timing controls. Gadzooks, timing added, subtracted and multiplied.. for cloudy days, rain, snow ect.. j/k...
