[fourload]

TD Powertrail stock muffler. Good gas (91 mixed with some 93 ethanol).8900 rpm . Noticed the DET lights light flicker for a split second during full throttle acceleration on hard lake chatter bumps. Very good traction.Runs low 15
’s on the dash PSI . I am thinking just drivetrain noise?

Put in some better fuel or good octane booster and see if it goes away, if it doesn't, it drivetrain. If it goes away, its fuel. Know that timing is being pulled if it lighting the dash too which drags power away.
