I've decided that I am going to do the following this weekend.
1. Pull and check all of the plugs for damage/di-electric grease in the wrong spots.
2. Clean and re-grease the COPs and boots.
3. Pull and check the CAM position sensors.
4. Pull and visually inspect the VCT solenoids for any damage.
5. Check and and clean fuel injector rail connectors.
If I find any issues I will replace/repair and then test drive. If the problem is still present I will do the following:
1. Return truck to stock tune
2. Confirm that the problem is not present on stock tune (which it has not been since I replaced the plugs/COPs).
3. Update the gryphon via pegasus and load up the canned tunes.
4. Flash my truck with the canned 87 tow tune. Test.
5. Not sure what my next step would be. If the canned tune is fine, I would suspect something up with the custom tune. Perhaps this:

I guess the next logical step after that would be to open a support case with PHP and see what they say.
