hey. so i put on that aem intake the polished headers and did full exhaust and i PICKED UP 13 horse power!!!!!!!. i was able to get a deal on a dyno right after so i went for it. took a while but aside from the 13 hp gain i lost alot of loww end torque???? WHY?>?? how can this be fixed

 

Post the dyno if you can. Larger intake and exhaust can decrease low end torque because their larger size makes them more suitable for the greater air flow at high rpm, making more torque up top. The larger piping reduces the velocity of the air at lower engine speeds.

A good solution for a loss of low end torque is forced induction.

 

yaa actually the guy was talkin to me about a used turbo he can give me a deal on. doesnt 13 hp sound like much from jus headers intake and axhaust, i was expecting like 7 or 8.

 

post the dyno
