This one is concerning the pinging under hard acceleration. It is supposed to be a computer recalibration. Saw a mention of it in 5.0 Mustang mag. Nov. 01
I just started noticing some ping on mime this weekend while on a trip. I tried some premium on the return trip and the car ran great. I think I'll keep the original program and the potential extra timing and run some premium when I go racing.
i work for ford, if you take your car in you will lose some performance, the update is to lower timing, just run higher octane fuel in it and you should have no problem
