Guy's, need some help here. I'm getting what I can only describe as a fuel rattle or pinging while crusing on the freeway. The rattle goes away as I put my foot into it but returns when I return back to cruise speed. I'm running a Super Chips programmer set to tow-haul mode and have no other mods.

Any thoughts ?

 

Try unplugging the chip and see if it does it.

 

I'll give it a try, if the rattle does go away do you think I'll run into the same issue with another brand of tuner?
