That's part of my plan now. I'm going to get a vac block and use the large vac port on the manifold that used to connect to the evap solenoid.
I purchased a TurboSmart dual stage mechanical boost controller so I can work my way up to 10-12psi.

I updated the overly rich 12psi IHI tune last night and loaded up the leaner tune today. The tun is basically dead on now where I want it (11.0-ish AF) in WOT. The only timing the knock sensor pulled was actually between shifts. I think that is due to needing to reset the IAC as the RPMs are hanging a bit.
At 7psi the log is showing 790 MAF counts. The max MAF counts at 12psi with the IHI was 880, so the GT2871r certainly seems to be flowing more air.

The spool time is great, and the respool time is even better. I'd say the GT is basically the same spool time as the IHI. I'm not sure how since the IHI is such a smaller AR turbine, but I'm not complaining.
