anyways here is my problem i took it to mac autosport to have it tuned today and got the motor running real nice starts up good, real good afr's all the way up to 4800 rpms where is hits a wall, it seems like a definite rev spark/fuel cut rev limiter the engine acts exactly as a 2 step launch control would no matter what everytime exactly between 4800 and 4900 rpm it goes strong all the way up to that point and then starts shooting fireballs etc etc flat out wont do anything more as far as settings go launch control is off rev limit is at 6600 soft cut 6800 hard cut neither my tuner or i can figure out what the heck is going on with this thing any suggestions? if need be i can upload my tune and some composite logs etc if you have any questions that may help you to help me feel free to ask away
