yea i have no trouble whatsoever spooling quick. im running a shirtbird log mani and a t3 .42/.48 and im hitting full boost(8lbs) around 3200-3400 rpms. full 2.25 charges, and 2.5 straight exhaust with nothing else.

oh yeah, I'm on a DSM T25, 2.5" charge/down pipes and dsm 450's on VAFC.

thats what it is, I remembered when I put the turbo on, if I opened and closed the wstegate by hand, sometimes it would stick open just a little bit, I thought that with the actuator, it would pull is shut easier though. Hum...any ideas on it. It almost like sticks open like 1/4 way.

If your wastegate is slightly open that will kill your spool times.

Also, even a tiny *** exahsut leak pre-turbo will ---- up your spool time.

Fix that ----. :P

I have a small IHI, it started acting like yours, I would have to floor it and I'd be lucky to make full boost by redline, I went over all my bolts and found two of the four bolts that hold the turbo to the manifold just slightly loose, I tightened them up and it fixed my problem, so don't count out that small hole as the source of your problem.

I'm hitting full boost now by 3500 or so, and it holds it all the way to 7500.
