Ran this same tune for almost 5 years now with zero issue, but recently got bored. Just pulled the turbo off 3 weeks ago and sent it in to FP to be built into a JB Black, ported stock intake/exhaust manis and 65mm TB, FIC 1250cc, 4" intake and Tial Q all waiting to go in once the turbo arrives. hoping to make a safe 500 hp+ on e85
