what kind of increase in power should i see at the rear wheels after i put my FMIC on? its a homeade kit....forgot dimensions but it is a bigger one with 3" piping. i have a 10# pulley now and will prolly have to put a smaller one on for the same psi....correct? thanks in advance for your input guys. :SNSign:

without a pulley swap you'd probably see a 5-15hp increase. with a pulley change probably 30-40. it's all going to depend on the efficiency of the intercooler and the amount of timing added.

with a pulley swap (3.5 to 3.4) and a power pipe i lost 40 hp with my first IC

tune was not able to be adjusted. Mongoose tune from MPH is VERY VERY safe!!

did you get a retune? or just let the adaptive learning try to adjust?

it had the tune from MPH on it still. i adjusted as far as it would let me but the timing was still very conservative.
i found the best answer to getting more power was 11 more PSI

it's all going to depend on the efficiency of the intercooler and the amount of pressure loss / drop it has.

(Boost PSI + ATM PSI) / ATM PSI = Pressure Ratio
Pressure Ratio * Air Temperature Ratio = Density Ratio
