My car is having really bad overboost issues in pretty much every jb4 map right now I have all the parameters pretty much untouched since I don't want to make things worse or blown car up it will make 36 pounds and blow the tires off at 4500 rpm maxing out my 3.5 bar and kicking me down into map 1. Could be a faulty Mac solenoid not sure im tryna get some help from Terry as well because I'm more familiar with flash only setups. I made a custom map 6 that I tried to target 16 psi but I made 36 so trying to diagnose with Terry what to do. He recommended me to set duty bias to 50 across the board in map 2 and see if I have boost control like that.
