I have the quad 110 and edge juice stacked on my 2004.5 truck with the lly motor. My question is first thing in the morining when letting the truck warm up on high idle it makes a loud popping sound that shakes the truck, but it only does it one time and only during the first time starting for the day. Anyone have any ideas on what may be causing this and is it going to hurt anything. Thanks in advance.

Remove the quad program and see if it still does it...
