  3. 1999 Mustang GT Odd Shift Points

    4.6L Tech
    The car is an auto. I recently got tunes from Brenspeed and they're all good except for when I'm just driving normally through town, the car revs north of 3000 RPM until it shifts after 1st gear. Is it the tunes or is my transmission about to kick the proverbial bucket?
