Latest email,
Spent most of the time building cylinder to cylinder compensation table reworking the trim tables with the manifold change. Fueling is tuned up to 13psi now with some timing added power will start to come up tomorrow.

OK... Just finished talking to Bryan... Tightening the wastegates helped hold boost. Car is making 530whp @ 14psi with little timing on 93 pump. Pump tune should be finished today and around 18-19psi. Power is very smooth. Dyno graph and video coming soon once pump gas tune finished. After that... Shell URT Unleaded Race Gas tuning....
You should easily get to 650whp on pump gas at 18-19psi, and IMO that is more than enough fro a street car. Most guys try to keep that number around 600whp....so I wouldn't even bother with the race gas tune, unless you will drag race the car on race gas.

Vince (tuner) told me that the tune (93 pump) was conservative, and that he felt like there was still 30whp left in the system with and a couple of more PSI. I think that if this customer had the .96 a/r housing 650whp would have been no problem at all.
The stage II kit comes with a larger 67mm turbo, and I am confident that 650+ whould be a reasonable estimate of max power on pump gas.
