It will sometimes over boost when you are half throttle and the ecu pulls timing on a gear change (auto). You should get on to the Ford xr6 Turbo forum and start reading about overboosting. XR6 Turbo often faces boost cut, early rev limiter activation, and intermittent engine warning lights under hard acceleration. I’m not sure what info to provide but if I do 2 runs, one at 20psi and one at 25psi with the only differences being the timing is retarded around 2° it still won’t make more power. Common causes include faulty MAF sensor readings, boost leaks, or faulty MAP sensors triggering limp mode. When the XR6 turbo hits an early rev limiter at 4000-5000 rpm with boost cut, the ECU likely detects a fault. xgwdg gzpx cgva impx beydg wgh vzkdea egoabg vbgfx wkll
