My serial cable came in today so I updated to 3.10 and ran the ground to share the PCM ground. I took it for a drive and flogged it a little. No more Chinese but I still can't get above waste gate psi. I changed the dutycycle from 40% to 80 and then back down to 20, no effect what so ever. My PSI start is at 9 and PSI end is at 11.5. I ran the solenoid test via the configuration menu but didn't hear anything. I thought the mac valves were noisy? I wonder if the Mac valve went bad..
