Not sure What tunes it is. it is a Ts chip. dont thing it has ever been re burned. i was hitting about 1200 with the 6 stage chip turned all the way up with just the 4in down pipe and a 3ft sec of 4in pipe after it before i put the stacks on. and i just put a S&B intake on it. and i am pushing like 32 psi with my stock turbo when i get into it.
