The biggest problem is how much his IAM dropped. On the 32 bit ecu's, they should be at 1.0 (FXT, STI, LGT 06+ WRX)
His should have been at 16...plus that was only a day of driving with those mods. It was really bad really fast. Also, he's running very lean above 50g/s AFR. When I verified his actual open loop AFR's, with my wideband, if was more lean and needed his maf adjusted a decent amount.

Also the high RPM fine learned knock is not good. He also had a lot of feedback knock, which isn't shown.
