I've been having a problem when I have my jb4 on map 1,2,5 and the car hits 15lbs it falls on its face and has a misfire. Once I turn the car off and then turn jt back on its fine. The misfire changes from cylinder to cylinder when it happens. Plugs were changed with oem bosche.

I took it to the dealer stock and that was a lose cause cause they couldn't make the misfire happen seeing it would only happen when the car hits approx 15lbs which doesn't happen stock.

Thinking maybe the map sensor is failing? The car runs no problems under WOT with the jb4 off on stock 5lbs. I cleaned the sensor off and tried it and that didn't help. Possibly it's failing under the amount of pressure? I don't just wanna start throwing money at random parts. Thought I would see what other people may think or if anyone had the same issue.
