Getting KR only when A/C is on.

So, I think I have my tuning almost complete but I have this one nagging issue. It is causing me some grief. I have a 2000 Silverado with the 6.0L swap, whipple S/C w 6psi, and 4.10 gears. I have also put in a built 4l60e, but the main problem is when I have the A/C off, the truck runs great, with very little KR, but as soon as I turn it on, I get upwards of 8 degrees! I have posted my logs and tune. Any ideas would be awesome. Thanks!

Hmmm... the knock sensors may be picking up noise from the AC compressor (if it's not loose).

Joe, sorry, I was tired last night. I left out a key piece of information. Normally when I get the KR, I hear a click, which sounds just like the clutch engaging and disengaging. The other thing is the A/C does not feel hot like the compressor is cycling. The only other thing I know in the tune that I turned off that was related to the A/C was the A/C parameters in the Idle section of the Engine Calibration. {B4358 and 59}.
