yEAH, 16* IS HIGH. fOX 5.0's can handle a bit higher timing than the sn95's9psi 98 said:I ran 14degrees of timing on my 88GT 5.0 and it was fine. It was just enough to wake it up, but I still ran 93 octane in it just to be safe.
Are you tripping the Check Engine light?? I would lower to timing to 12* and see what that gets you. If that doesn't work then lower it to stock 10*. If no go, it is probably more to do with a sensor(s) than actual octane/timing.Demolisher said:Well today i ran 93 octane and it still was pinging does that mean i have to lower the timing?
