OverBoost w/ JB4 & BMS flash

I'm having overboost with my modified BMS Race Flash (E35) & JB4 map 6 at ~17psi peak, just wondering how to comprehend the WGDC (main) table to make adjustments for this, I'm getting throttle closure and I can't feel it....but I hate it....so so so much


Any help would be great! thanks!
