Well guys, what Dan said originally is basically the truth, unfortunately. When we originally started tuning the car, it was on a 2.8" and a fresh tank of E85. We drove around on the highway for a little trying to burn off the majority of any pump gas that was still in the tank, and that's when we started playing with it. At part throttle it was boosting just fine, no KR, pulling great and running smooth. After a while, that's when he started WOT pulls to test out the tune and scan for different parameters. Again, almost no KR ever, and solid strong pulls. On one of the pulls though, it started misfiring and I thought the worst to myself. I ended up pulling plug number 5 first and there it was, a smashed plug. I could have cried, but I decided not too lol. Re-gapped the plug and went around and tried it again. Second time around and bam, another misfire. We noticed on the second pull that AFRs were spiking to 12.5+ and figured that was why we chipped two pistons. Fast forward, I ended up going home disappointed at 3am after all this. I get a call from Ryan the next day to check for MAF frequency on my Aeroforce because he studied the charts he had and noticed that I was maxing the MAF frequencies out. I did a pull in 1st gear to see, and it hit 11.5k on the MAF frequency which he said was the reason why it leaned out. So I'm guessing that's my issue.
Basically I don't want to dump anymore money into this thing, especially knowing the rust issues it has. It is what it is, and the damage is already done. Gonna put a new set of plugs, and maybe a new MAF and call it day and sell it. It hurts me to see it go, but I'm starting school this fall for the first time since graduating high school(3 years) and just need to take a break from all this, considering the bad luck I've had with it.
I appreciate everyone's support about the situation, I definitely won't be leaving GPF, there's a lot of great people here, but I think I'm moving on to an AWD turbo platform

Volvo S60R or Saab 9-3 Aero to be exact :th_biggrin2:
