What manifold you running ?

Nyther

Greddy cast manifold. Why? There isnt any other manifold to use that produces more hp on this kit. The only one in existence (pfab) performs almost the same..

S2KCHRIS305

Just asking cause I had the pfab mani on n I couldnt get.passed 246whp . Swapped back to.greddy n got 278whp on the first pull without touching the tune yet

Nyther

Well the pfab mani tends te NEED a retune, which makes sense since the runners are slightly larger and slightly different curvatures. im guessing the retune will fix that problem. when are you going for a retune?

S2KCHRIS305

I did tune it with the pfab

RedSunS2K

I have a pfab replacement, and have a little over 300hp tuned on dynapack.

Nyther

So the pfab actually performed like crap? Thats odd. Who else has this issue?

S2KCHRIS305

i guess its worked for some people . but theres alot of cases on here of people loosing power when they switch to the pfab mani . it happend to guamie . i made 270whp and 220trq at 7.5psi on my greddy manifold ona dyno jet 224x. i couldnt get passed 240whp at almost 9psi with my pfab mani

S2KCHRIS305

what other mods you got done to the car . such as exhaust and test pipe ? and what psi are you at ? also where did your tuner put vtec at?

guamie

i posted my graph and people are saying that it's my tuner. Most people are suggesting to raise vtec engagement. has your tuner tried that? I'm going in for a retune soon, so i will post my results later.
