It doesn't seem to do it when it first starts up ( I can never remember if that's open or closed loop). I'm not sure what you mean by posting the tune up. It's the stock tune as far as I know, or what it was when I got it, with 3 degrees pulled out from 3000-6000rpm at WOT for the spray with a predator

Ok. Installed a stock maf and a new TPS. No change. When it's cold started and in closed loop it runs perfect and a/f is 14.5 at smooth idle. as soon as it goes to open loop the a/f starts climbing till it pegs the meter at 21.9 and idle gets kinda rough. If you rev it the a/f reacts as it should but when it drops back to idle it leans way out again. does the same on very light throttle cruising
