You're overboosting and trims are in open loop.

Try resetting adaptions by selecting 1/7 with the steering wheel controls with car on but not running. However my guess is that this is some sort of hardware issue. Car isn't running correctly with the Jb4 defeated.

Trims are pegged at 50.... And AFR's are pretty lean on those.

Best way forward, add in the free PUMP back end flash to extend your fueling range.
