TURNER SAYS ECU MAY HAVE WENT BAD AFTER HE REFLASHED W/UP-REV. MY CAR AT TIME WILL RUN GREAT THEN OUT OF NOWHERE IT WILL FALL ON ITS FACE(NO PWR). I WILL TURN THE CAR OFF WHILE DRIVING AND START IT BACK UP. tHIS SEEMS TO CLEAR THE COMP. AND IT WILL HAVE THE PWR BACK. tURNER SAYS HE HAS BEEN BACK AND FORTH W/ UP-REV AND HE OR UP-REV HAS NEVER SEEN THIS. HE SAID HE IS REMOVING THE ROM AND RETUNING FROM SCRATCH. (( WHY HE DIDNT DO THIS IN THE FIRST PLACE I DONT KNOW)) BUT HE SAID THAT IF THAT DONT WORK HE DOESN'T KNOW WHAT TO TELL ME..... ANYHELP WOULD BE GREAT THAXS

 

That 'limp mode' could be the excessive detonation map kicking in due to poor tuning. Honestly if your tuner can't figure it out maybe you need a new tuner?
