Hi there. I have a 95 gt with vortech SQ2 supercharger and msd boostcontroller. Does anyone have any idea why I cant get the car over 5700-6000rpm?? but the power up to that is ok..... Beat the %^@ out of my brothers 95 camaro F1 But I know it has more and I want it. ... Does anyone have any idea what this could be?
Thanks sverrir karlsson iceland

It's most likely your rev limit in your PCM. Once your go above your set point, it cuts off your fuel. It seems a like it's happening early, but the tachs aren't always that true.

Another thing to consider is..............

If you are running the stock E7's you very well could be floating the valves due to weak springs.

well before the sc install the car got to 6500rpm without any thoubles. Could this have something to do with the MSD boostcontroller? or what can this be?

Click to expand...

That would lead one to believe valve float is not the prob.

If you think if might be possible that you are blowing the spark out try to close the plug gap a little and see what happens.
