I'm posting for a friend from Facebook. He was on a JB4 and IS20 with no issues. He even ran as high as 27 psi tapering to 20 with no issues. He wanted to flash because he wanted to remove the speed limiter and be able to do left foot braking. He had the car flashed to stage 2. There wasn't an IS20 tune available. He drove it enough to do one map 4 log and then ran it down the 1/4. At the end of the run it lit up like a Christmas tree. He has cylinder 2 misfire, random misfire on cylinder 1. Cylinder 2 is permanent. He tried switching coil packs with no luck. He pulled the plugs and three are fouled despite having just put them in, and the cylinder 2 plug was cleaner, but funny looking. Cylinder 2 has oil in it as well. He did a compression check and cylinder 2 is only 30 psi. The others are 150. Here ar the plugs and the graphs of the pulls he did with map 4. What I find odd is that he hit 28psi on the flash which is designed for the IS12. I know others on here have stage 1&2 and then did IS20. Would love some feedback
