Has the ECU ever been reprogrammed for the 24 lb injectors??

Stock ECU's are programmed for 19lb injectors.

If you are running 24's on it, that could be your problem.

IT HAS A 76MM C&L MAF W/24LBS CALIBRATION TUBE ON IT. I'VE HAD THIS SET UP FOR SOME TIME ALREADY AND IT WORKED FINE UNTIL NOW THAT IS BOGING BAD.
