knock retard around 2400 to 3000 rpm cammed lq4

swapped a stock lq4 into a 2004 gmc sierra and drove it for over a year now with no issues. i pulled the motor and put a summit stage 1 high lift cam and replaced all gaskets while on the stand. put a 4l60e high stall converter that is specd to stall at 2400-2600 behind a 5.3 engine. while getting it dialed in i am intermittently getting knock retard when i go to roll into the throttle. it has ebay stainless long tubes that ever so slightly rub the frame one one side (even after beating on them for clearance) but they were on the truck the whole time the 6.0 has been in it. no wot pulls because i am waiting on harness adapters for my 50 lb delphis. if someone with experience can take a look at my log and tune and see if anything jumps out to them i would greatly appreciate it. also i set all cells from .56 to .92 at 13 degrees all the way across the board and it still said knock retard in that area twice but not every time i lightly roll into it.
