pinging question

[Mustanggt108]

with 93 tune i get some pinging , but its not THAT loud and noticable.Its only at WOT around 3500-5000rpms . Is that really bad? do i have to go back to 91 tune? If i run the car and race it like this, any problems?

Sounds like it is actually cats or a heat shield. Does it only do it under heavy load???

How would that be the case if it only happens when he runs 93 octane?

Detonation is no bueno!! If it really is pinging, I would try backing off the timing a little bit, or going to a "91" tune. Dont even have 93 where Im at.

Oh yeah... I based my assessment on the fact that he gets pinging fairly low in the rpm range but I guess that is possible as long as it is WOT and under heavy load.

lol Kilgore.Well it does it only at WOT as i stated.and only with 93 tune .When i drive it normal there is no pinging , and with 91 no pinging at WOT or normal.I might try to pull timing a bit and see what happens

Well are you using 93 octane gasoiline? I have seen some use less when they have a higher octane req tune.

If you have a tuner, I would pull some timing just up top where it happens and see what that does. No need in pulling it in all ranges unless needed. If thatdoesnt work, try and switch to a 91 octane tune, and still use 93 octane and see if that helps.

It would be OK to run it like that for awhile but I wouldn't advise it, as it's pretty hard on your pistons. It also robs valuable HP.
