New poster. Tried to look through old posts but not sure covered. 2001 Mustang GT. V3 Vortech. New 300LPH fuel pump and filter. IAC, FRPS, upstream O2 sensor, and TPS new. 525 fuel clinic injectors. Had low VREF constant codes. Did all the checks and finally pulled the pin and got a new PCM. Hand me down car and PATS was cut out so got a tune from a reputable email guy. Problem is it stalls immediately on start up unless given gas. Warms up and stabilizes but still hunts a little bit. AC makes it run super lean at 32.8 STFT. Put a vacuum gauge on it and it jumps a bit. Looking at the video, does it bring any alarms up? Also noticed the BOV is extremely quieter than before. Haven’t done a boost leak test yet but will. Not sure how old the belt is but no visual defects. Tensioner jumps a bit but not sure if it is jumping too much at idle. Also new plugs and coils. Update- did the video upload? Not sure.
