I just acquired a 2003 Silverado that had a 2000 Yukon 5.3 swapped in it. I'm currently trying to tune the VE table but some weird things are happening. I'm not super proficient with tuning yet but I have been reading through the tuning school books to try and get it dialed in. The issue I think I'm having is my wideband is reading different than my LTFT when I log. It seems like its running super rich and I keep trying to lean out the VE table but I feel like all I've done was make a hole in the table and it still runs rich for some reason. I'm not making any progress here and would appreciate the help!
Specs:
5.3
241 heads
headers
no cats to 2.5 exhaust
Summit SUM-8709R1 cam and springs
Stock intake, tube and air box
Here is the tune that's on the truck and the latest log I have
