The retune was done today. It looks like I gained 10 fwhp from my new 4-2-1 header, and another 20 fwhp from the retune with the injection system. I'm now at 202 hp and 194 lb-ft. of torque at the front wheels. Although I'm totally happy with this, and the car is quite quick now, the tuner was very cautious about timing advance increases. He raised the AFR from about 11 to 12-12.5, which the car liked a lot, but he only raised the WOT/high RPM (high boost) timing by 1 degree to 16.5. He wanted to play it safe. I have no problem with this, but I am curious if we could have bumped the timing advance up more. Either way, the car is a blast to drive!
Thanks to everyone who helped! Oh, and my previous post comment about the drop in gas mileage seems to have been a fluke. I think it stayed about the same after the kit was installed. With a higher AFR now, I would expect slightly better mileage now, perhaps.
