I just resently did this swap, motor was square decked head resurfaced, crank turned and polished, new bearing arp bolts apexi head gasket, and ssqv with front mount.

It runs good until you get on it. It will pull (kinda hard) then at 5k it will pull even harder

. And then it will also backfire. It has stock injectors and turbo, just hks hi power exhaust. Any ideas?
