Strange fuel issue?
 
Alright so I've tuned my car pretty decent but every once and a while when I'm drifting and high up in rpms my afr goes retarded lean 22's and my motor would literally stop momentarily killing my drift.. I've watched my wideband gauge while I was doing donuts and it would be solid 11s under boost and high load high rpm then my motor would just cut out almost as if I let off the gas and my afr goes lean to 22. I'll see if I can get some data logs next time it does that. Anyone have ideas?
750 primary
1600 secondary I'll post up my maps tomorow
