It's makin 331@248 on a mustang dyno, it's pushing 25PSI should i be making more power? or am i maxed out on this setup? If so what should i be changing out first to get some more power? I've had it up to 28-29 PSI without any gains just pushing hot air. Lemem know what you guys think i wanna be makin around 400whp. Thanks in advance.

 

look into cams. get at least gsr cams. there can be had for $50-$90 in the classifieds. Ur power seems low. People are making 330whp on stock ls/vtec's with way less boost and no meth kit. There seems to be a bottle neck in ur system somewhere by the power ur posting and the amount of boost. But deff invest in som sort of cams.

 

I would say that your down on power, espeicially for the boost that your pushing, but looking at your set up, it seems kinda restrictive. The 2.5 inch DP and exhaust and log type mani aren't helping you any, and you probably want to get a bigger intercooler aswell. Still, for the amount of air your pushing, it still seems low, but I'm not an expert, just my opinion. Change that stuff and I bet you see a huge gain.
