ok i used to beable to rev up to 7500rpm but since i put on my msd i can only go to 6500rpm, is it restricting the revlimiter even more or do u guys think that i was never actually revin to 7500 and the msd just fixed the tach?
thanks

 

What engine, ecu, and msd model you have?

 

well, im gonna take a shot in the dark since we dont know ur setup....

maybe the msd rev limit is set at that???

 

thats what i was thinking but i want to see if he even had an h22

 

o sorry guys, i have an f22b in there, the only reason i have that engine in there is so it runs, but it has the f22b ecu with it ,and i just have the sport compack box with the blaster,and wires , no distrubuter.
