all i know is mine is at like .56v and it makes a huge difference..

ive seen guys running pig rich for some wierd reason so we set the tps back and no more pig rich???

but iam just smoking bad crack! Someone please clarify
All its doing is adding more fuel when the engine does not really need it, what you feel is a little more snap when you crack the throttle bwecause its sort of like getting more accelerator pump shot, on some cars this can make more snap, but on the minus side the engine will run too rich until you actualy hit WOT, costing you part throttle power.

I can assure you that it doesnt make any more power, nor make your car any faster, you just feel some more transitional snappyness and it is fooling you to think the car has more power. Its like putting on a thottle body thats larger than your engine really needs, it feels punchyer but really makes no more power because its just like opening the throttle more with less pedal movment.

Like an SR20 feels a lot faster with a bigger throttle body but it really does not do anything on a stock motor. Some motors like GA16's the bigger throttle body actualy does something.

Add a lightened flywheel.

Subjective testing doesnt mean anything. Put it on a dyno, you wont see any difference.

Same for u, add a lightened flywheel. No hp gain but faster 1/4 mile.
If ure engine hp peak level is at 5000 what would u say if it stayed longer at that peak?? no hp gains but would it change youre 1/4 mile time??

Cheers.
