Default 04 GTO with Maggie/ Headers retune

I was able to work with Eds car on Saturday afternoon as we were curious what numbers he was putting down and what could be pulled out of it.

He had been running 12.2 at infineon raceway very consistantly. I am excited to see the track times after our tuning sessions.

Run file one GREEN was a base pull with no changes to his tune it made 405 rwp and 401 tq this is with a cold motor with IATs in the low 100 range

Run file 6 RED was a duplication of the timing curve that the car put down at the drag strip based off of a log made while running the 12.2 the timing was pretty flat at 17-17.5 * mainly due to how his original tune reacted to actually driving the car and building heat rather than just a dyno pull and cooling time,it made 395rwp 392 tq

Run File 5 BLUE Is what the car left with the shop with last night and with IATs from the maggie at 160-175* after running the car on the street it maintained my final timing curves at the above temperatures with no detonation and running half a point richer on the wideband. This final tune makes 421rwp and 402 rwp.

The variations in the peak tq numbers are only because of where I tipped into WOT on each run so run 001 spiked a bit at the hit. look at how much the TQ carries out now vs. before as well as the horsepower where it matters.
