Ironically, mine just started making this noise today.
Or at least I've never noticed it at idle until this afternoon. Today i drove with windows down so didn't notice it on way home, and didn't notice it all today going in to work, or when i started it this morning (idled for 5 minutes or so waiting on school bus to picks kids up).
Definitely sounds like metal tapping metal, not a consistent tap, and seems to sound more pronounced from under the truck, around the down pipe area. at times it seems to come from the driver side. Going to put it on stands here in a few and let it idle to see if i can narrow the area down more.
I have boost defuel set at 32, and engine coolant set at 120 * F, and I've never gone higher than the 60HP tune on the MM. I've done a few WOT starts (can count on one hand and one hand only
) when BIL and I are out with his F-250. Generally, it gets driven 'normally' so i don't kill a HG or 68RE. Point is i don't drag the truck and don't drive it like a space shuttle.
