Your lean, and try a range colder plugs (7's) or two range colder (8's).
sometimes you need to add alot of fuel to get away from the popping (there are two sides of the 'good tune curve', you can be way lean and it acts kinda rich when you barely add fuel, or you can be way way rich, but when you add fuel to that, nothing changes.
Try doing a pull at 0 on the afc and see what happens and lean out from there.
tps should read 100% btw.
