I'm tuning a 07' LS7, T56 with mods...TSP stage 3 cam, Holley intake, Nick Williams 103mm TB, FIC 60lbs injectors. The car idles and runs great rolling into the throttle clear up to 7k, but if you stab the throttle, then it feels like it's hitting a rev limit at 2500-3500rpm. Any ideas of what can be doing this? Thanks in advance!
