money seems to be an issue but if it wasnt i would go with a ported head and a good valve job, that will definitly yeild you some power. but you are talking some money

Stop giving out bad info.

His turbo uses a stage 3 wheel, with a 2.5" outlet on the housing. He does not need a 3" DP for this power level. Yes it would be an upgrade but wouldn't fix his problem.

Ive seen the same issue with other tial knockoffs 38's..

 

What D series motor is being used? Stock Z6 head will support over 400whp, no its not the most efficient but it'll make the power.

Only thing left here looks to be the FMIC. Get something quality and get away from these 2.5" thick China knock off junk. You'll notice siginificant gains just from a quality core.

 

yup ug ot the turbo right...

i dont think the head is an issue yet, i do think the dp is, and the ic was, and the wastegates innerds are going to be tial parts now, so im slowly canceling out problems i could be having... tonight im going todo 3" dp nad see how much that helps,e ven if its connected to a 2.5" exhaust

 

yup, its z6, ive got a new fmic, its not the best, but we will see if its good enough, if not im investing in a precision soon...
