Main issue is, under hard acceleration/full boost the engine stutters cuts out as if the over boost is cutting in. bypassed the over boost switch by sending to ground, that made no difference. Have checked rigorously for air leaks and I am 100% confident that there are none. Changed all the red relays. and eventually took to local Porsche specialist to have the fuel pressure checked. Pressure was fine under normal conditions. Whilst there they checked the warm up regulator and that was working correctly. They took the car for a test drive and without further investigation and 's they could not identify the problem. It is real strange, my first thoughts was a fuel issue, but if I accelerate smoothly she will go as fast as I wish but floor it and stutter/cutout but not stall. Am I missing something? waistegate issue maybe? Fogot to mention, the turbo now whistles constanly.
I just have the same problem exactly you have one week ago, I replaced the Over Boost Switch And Pressure Sending Unit For Turbo Boost Gauge.
Parts Number:-

you have to replace both of them in one time.

My car is working now perfectly .
