If you're using standard fuel pressure 43psi, your injectors are probably somewhere around 66%-69% duty cycle -- does that sound about right?

For fun, I just charted your 16psi dyno/boost graphs and marked up your dyno pull's progression through the GT35 compressor map. 440 whp is about 57 lb/min on a rotary, which at 16psi (2.1 pressure ratio) is right at the edge of the map. The turbo's most efficient point (79% efficient) is right around 270whp or 4500rpm and has dropped to 65% efficient at 7000RPM/440whp. Your turbo looks to be spinning at exactly 100,000 RPM at max power and 85,000 RPM at 3800RPM at full boost.

Thanks Jesse... still trying to reach Tony to see if your numbers are in the ballpark. I'll try again on Monday.

Thanks James and Jeff. I think you guys both understand how long this project was in process, so it's nice to get a result that exceeds expectations. Thanks again for your support and encouragement!
