So I recently bought my srt4, my afr cruising is 14.9.... I have good afr (12.5-13.9) when I floor it until I hit 17lbs I’d boost then the car cuts and leans way out 16.9 17.0. I have good fuel pressure and everything I have no clue what tunes on the car I didn’t get the tuner with it. I can’t tell if it’s boost cut or fuel cut or spark cut. I don’t want to blow the car up. What could be the issue because when I test drove it, it never leaned out. Now it leans out at 15% throttle, I have a mad ignition on it, stage 2 injectors I believe, runs on 91, car pops like hell when letting out of the throttle.
