My stock turbo is 21 psi by 2800 RPMs but almost every mod I have is geared towards spool with HP as a side effect.

 

Got some video of it this am. I did one 3rd gear pull from 2000rpm to 7900 to see what it would do here is how it looked:

3000rpm=5psi
3500rpm=10psi
4000rpm=19psi
4300rpm=23psi
4500rpm=25psi
5000rpm=26psi

With a very slight creep to 27psi by 5500 rpm. It will hold 25/26 in 1st and 2nd and only creeps to 27 in 3rd and 4th. I was a little suprised that the boost was only 5psi @3000 but it all happens so fast it is hard to watch the road and keep track of boost/rpm. The turbo hits really hard around 3500rpm and builds from there. I have the BR manual boost control set to hold about 25psi so the it looks like the last 1/2psi are a little boost creep. On a side note 3000rpm to 7900rpm (34.8mph to 91.6mph) took about 4.95 seconds.
