i get this rattling sound like rocks kicking up or somthing..DOSNT SOUND GOOD..when accelerating...around 2500 rpms...not under hard acceleration...just normal driving...i have the diablosport preadator in it...and stuck with the 87 octane tune...didnt change any paremiters to mess up the car...is this normal? ...it sounds like its coming directly from the motor...im not a gear head so i dont know what to do...

gosh... sounds like you car is possibly pinging... but I'm really surprised it would be doing it with out fairly hard acceleration... Might want to try putting in higher octane gas and see if that changes things... or pull some timing out with your Predator... hmmm...

that could be it..ill just install the 91 octane tune and see what happens..and add some premium
