i use to have cel during full boost just under redline, the problem went away after messing around with my safc settings, i think i was running too rich, so i turned it down some, and it never shows its ugly face.

i would also check your plugs, maybe replacee them.

under part throttle there is less gas. under full there is more and possible the plugs can't light it all off any more.

i used to have the same problem, fuel injector cleaner helped alot along with a new 02 sensor.

o2 is another good idea.

when things like this happen "Was running perfect for 3 months then all of a sudden started running like crap". I would first start looking at what things might deteriorate quicker due to the excessive fuel and pressure increases..

stuff like plugs, o2, injectors.. all cheap easy things to rule out.

huh, i've got kinda the same problem in 1st gear. It pops and messes up like that. The rest of the gears are fine.

After putting on my other o2 housing (with a DP on it) (which causes the flapper to be a tad open at idle), it doesn't seem to do it anymore
