I have a sloppy stage 2 cam in my 2006 Silverado. After installing a 2800-3000 stall torque converter, the truck has had problems returning to idle when going slow and occasionally stalling. I raised the timing up in all 4 tables and its not stalling as much but it still does once and awhile and it still doesn't idle correctly. I noticed the idle advance is kicking in when the truck is idling causing it to idle between 14-29 degrees of timing rather than the demanded 22 degrees, and idea what is causing this? Cam specs are 228/230, 585"/.585" 112 LSA.
