Whatever u wanna call it, I dont go for it!! cant stand 2 hear ir at all! been that way all my life, but anyway! sry bout that! ok just installed a used chip that was pulled from a Mach with the same mods, which is very little, and its great as far as thrtl response, burning much cleaner, turn traction off, but, im getting a little pinging if i go wot under load, and very little untill i shift and then it clatters, very little. and please spare me with the "what octane?, or chk your fuel filter" i take very good care of my rides and this is an issue with the chip, just wondering if ny1 knew y and what i need 2 do! wow, made that way too long, sry!

 

Take care of your car like you say you do and get a custom dyno tune.
