Kilgore Trout said:Sounds like it is actually cats or a heat shield. Does it only do it under heavy load???
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.OxMox said:How would that be the case if it only happens when he runs 93 octane?
Mustanggt108 said: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
Oh yeah, one should not cast stones...OxMox said:I'm not whoreing. I'm helping with his pinging problem.... it could be an STD

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.Mustanggt108 said: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?
