have someone boost the truck while you have the hood up and see if you can pinpoint the sound. I've seen a few where the elbow connected to the fuel cooler comes loose. There are 4 nuts holding the unit to the driverside valve cover gasket. Also check your IC boots for tears or leaks.

Not to be nosey, I was wondering how you guys feel when you take your truck into the dealership for issue like the ones above and you have done all of these mods to your truck. Do you just accept that the warranty is out the door and you will be footing the bill. I mean I can see taking the spartan tuner out but your not going to change out your 4inch exhaust. Just wondering.......hoping to have a spartan and dpf delete in the future.
