[Bryan_G87]

I recently switched from Racechip to JB4 on my M2. I had seen some other G8Xs get some good numbers from running E85 blends and decided to try my luck. Worked with a guy on one of the JB4 facebook groups to get a custom map 6 tune for an e30 blend. The drivability of both seem to be similar. They both drive smooth as stock in my opinion. I could push the JB4 farther, but I am traction limited and had to dial the boost down and dumb down the boost ramp to help with traction.
