New numbers for my Mach1 powered GT

[Fastlane]

I finally got to the dyno for some tuning on my 04GT. I recently rebuilt the 4V engine that I installed a few years ago. This round it is fully forged with 10.0:1 pistons. I swapped the T56 for a built 4r75w from Mike's Trick Shift. I also installed a return fuel system with ID1000 injectors, twin 455 Walbro pumps, and a Whipple 3.4l crusher.

Manny Alvarez at HPP did the tuning - 100+ degrees in the shop and ~30% humidity. The car made 730hp/630tq.

The pumps are maxxed so I am installing a 3rd 455 pump and going back to finish the tune soon.

That torque curve

how much boost is taking to get to 730?

I have a 4r70w sitting at Mike's also, waiting on me to get home. Swapping out my T56 too.

25 psi to get the numbers and hoping for a little bump the next time I hit the rollers.

Solid #s. How's the drivability just cruising around town?

[Fastlane]

The drivability is fine. Idles normal, cruising at part throttle is smooth and effortless. I've only jumped on the throttle hard once briefly and that was shocking. I won't get any real pulls in it until I get the last pump installed and get the tune finalized.
