and what kinda gains did u see.. i have a CXRacing 22x11.5x 4 with 3" piping and only seeing 13psi with the blower maxed out...

25 psi on the blower side of the IC and 13 at the motor....

Any pics of the 4 " setups?

I only made 13 psi also spinning 4k short of max 3 in piping to motor. I to think ic is eating to much boost. I dont think 4in after ic will help i will try after new build is complete.

I would chase the intercooler.

Did a 2Jz the other day (T88ish) and we had something similar. Removed intercooler, boost restriction gone.

I think some of the stuff coming off of ebay doesn't flow that well.

intercooler or boost leak. Thats a LOT of difference.. How much hp are you making?

I don't think switching from a 3" to a 4" pipe is going to put you where you need to be. I would look at replacing your intercooler.

I have 3" piping .. and boost is to smooth for a leak my tuner says. So if 4" wont help that much it must be intercooler
