New to this but I was wondering if anybody has had an issue with acceleration, I currently have BMS intakes and a JB4 tune so far at 68k miles, I ended up adding 4 gals of E85 and the rest 91 oct I let the fuel mix for a day or two for the JB4 to read at e30 but as soon as I changed to MAP 3, my JB4 froze at maybe 50% throttle and stutters to climb as if boost isn't constant. Does anybody have any idea what's going on and what do you guys think i should do? I almost emptied the tank and refilled with regular 91 so far but my JB4 continues to cut out after going a certain throttle been noticing it freezes on my phone between 9 and 11 psi of boost.
