what does engine pinging sound like??? im just curious bc i feel like ive been hearing stuff since i've installed my diablosport but it could just be all in my head[>:]

i uploaded the diablo tune and changed around a couple things but nothing major. just shift pressure and raised the RPM's when im in drive...

and im still putting in 87 octane...

You're supposed to run 93 octane with the Diablotune. that noise you are hearing is detonation from your timing being advanced.

pinging will only occur during wot. so if its anything besides wot its not pinging. it will kind of sound like its coming from the dash. you will know hwen you hear it.

At least run midgrade gas.... not that 87 ****. I'd still run premium in your 6 bangerif i were you.

umm. i am guessing you have a GT (since you asked it in the 4.6L section) and from the body style a 99-04. with or without the diablo tuner you should have been running 93

actually i have a 6er but i just wanted to hear what you guys have to say b/c i feel like the 6er section is dead lately.. im not bashing my own section but i figured its the same noise wether its a v6 or a v8 so why not ask??

and thanks for the help. if its only at WOT thanmine's not pinging

this isnt a GM we are talking about here. you dont have to run premium on a car that hasnt had its timing modified. they are designed to run off 87 octane.

WRONG. The best way to tell if your car is pinging is to go up a hill with steady pressure on the gas, but make sure it doesn't down shift. This will put load on the engine and create any possibility of a ping. This will allow you to actually hear the ping vs. struggling to hear it over WOT exhast and engine scream. Any load on the engine will cause a ping if it is in fact pinging. I like the hill test. My truck does it all the time with 87 octane up a hill. Pinging sounds like poprocks candy in your engine (lol) or like erratic valve noise.
