I have no oil cooler and 100k AT. Ive been boosting with meth for 60K. If JB4 had e85 maps back when I bought my car, I would have never needed all my mods. DCI and some e85/93 mix on map 5 and you have a 12 sec car with 400+ at the wheels. I'm ready to start selling parts just to get my $ back because the autotune map for 85 changed the game. Car runs cooler burning alcohol. My meth injection no longer needed to achieve whp and boost up at 17 psi. All the tunes are the market today are amazing, its hard to pick for sure but if your budget has you considering JB4 then you won't be disappointed. Don't be surprised if you get bitten by the tune bug.... piggyback and an intake is how it all starts.
