I recently bought my 98 GT from a buddy of mine and he was telling me to just use 87 octane. Ive been going back and forth every tank between 87 and 89, which seems to be working out fine so far.
My real question is this:
I just ordered a diablo predator tuner from American Muscle, and to my understanding it has a tune for 93 octane, would it be in my best intrest to use that tune and start putting the higher grade gasoline in my car?
Does anyone know if theres a tune for mid range gas?
