Hi guys
Car seems to be dropping fuel pressure only at a specific point. Car is a MKV gti stage 2. It meets peak requests of 109,9 bar and is completely fine through out the rev range except for between 3800rpm and 4400rpm.
Starts off high, at 109,9 bar, drops to about 80bar at the above mentioned rev range, and goes back to 109,9bar immediately after.
Can it be the entire pump that is faulty or just the sensor on top? Or something else that im not seeing?
