So what should I tell my tuner? The car is running pretty rough. By rough I mean it back fires at high rpms and the car feels like it shutters real bad. Also when pulling out in first gear the car feels like it lugs really bad then kind of comes alive at about 2500 rpms...

is it throwing any codes?have you checked the plugs and wires,and or checked for leaks around the intake and TB?i would check for any mechanical issues before taking it back to the tuner(bent pushrods?).for the street i would shoot for around 12.8 to 1 AFR..but maybe that combo works a little leaner?i'm not familar with the TFS heads and what they like.i would think the stock fuel pump would be ok,do you know the duty cycle of the injectors?

Ok so since I installed the H/C I have put on a few more goodies. I now have 1 7/8" kooks along with their true duals, monster stage 2, tick master, FAST 102, a new fuel pump and I plan on going with a SD tune. I originally put down 426/414. Any guestiamtes as to what I will be putting down now? I will post a dyno graph after its tuned.
