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.
