So I recently replaced my diaphragm in my regulator because it had a tear in it. I went to take the car out today everything was fine until I got on the highway with some boost. I would loose throttle response and thought the engine had died. I was able to get it home and looked at my log. I noticed my boost was high relative to everything else. There was a spot in the log where the car died and I coasted to the side of the road. The car wouldn't start but a few minutes went by and it started fine. So I get it home and after a 45 minutes I go back to check and my boost gauge said 1psi and fuel pressure was at 20 which is odd. Not sure what would be causing this. In the log, I have a linear fuel pressure setup. Not sure what is going on here. All that was changed was the map sensor and diaphragm in the regulator.
