so after getting my sr back in for the third time i upgraded my turbo to an oem s15 spec r turbo.. im using a greddy profec b spec II and my read out says im making 6 psi but the power just isnt there its slowww.. plugs are gaped to .030... i have checked for boost leaks and vacuum leaks there are none.... i am running a draw through setup but because the turbo sits a little bit different than the stock t25 so i cannot run the hose from the bov back into the intake because it dose not reach... so i blocked off the intake hole would this make that big of a difference in power loss??

any help is much appreciated

blocking off that hole shouldnt change anything. So your now running atmospheric BOV instead of recirculating it? that shouldnt change any power, the only thing it would do is make your idle serge from the MAF not checking that escaping air because it dumps to the outside. id say check your fuel delivery? if your spark is good and your gapped right fuel would be my best guess.

instead of checking just for vacuum leaks. check to see if the vacuum lines are routed properly. I had this problem on a Z32 i had a while back.

I do not know if you have a separate boost gauge or just using the greddy unit. Is the greddy unit reading psi? or are you looking at the duty cycle (%)?
