i meant 10 degrees over what base would be. i have mine at 15 (total, so 5 above base) but when i bought the car it was at 10 OVER base and didnt really do anything except require me to put 93 in the tank. i tuned it back down to base right away because i didnt notice much of a difference between the 2.
EDIT: id honestly just put the car back at 10 degrees and leave it if the motor is stock. on a completely stock motor you’re really not going to notice that much of a difference if you bump it up 4-5 degrees, or at least i didnt.

You run an AOD. T5 cars the bump in timing is noticable. Bumped timing, along with gears, slicks, and exhaust were some of the main components in putting stock Mustangs into the 12’s, it’s good for 5-10rwhp. Also, if your car was at 20 degrees that’s bordering on detonation.
