Cruise boost is essentially not adjustable; it is around 2psi (regardless of actuator position).
The VGT on the VNT 15 is pretty darn awesome though. If you run, say 75% throttle to accelerate you will get around 6~8 psi of boost almost instantly. 90% throttle gets you 10~11 psi. Not like driving a wastegated turbo at all. For reference the exhaust wheel is just slightly lager in diameter than a US Quarter.
On that note, I am beginning to doubt my SGII readings. I drove 150 miles today (at highway speeds approaching 75) and am still reading full. Normally I see the gauge move off of full around 3 gallons consumed. So I'll go re-fuel in the morning and we can get an idea if my highway readings are just wacko.
