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
o yeah i have a f22b engine droped in with the f22b ecu if that helps,the only reason that this engine is in is so that it will run, but if u guys could help it would be helpful!

 

I could of swore there was a post about this the other day??

Maybe your ignition is set at 6500??? check to see if its at that and if it is adjust accordingly
