Running LEAN!! problem areas= Hondata+3Bar+O2+RC 550 p&h
Okay guys, this has been happening a while now but today it was at it's worst!! I need help!! while driving today, my a/f just jumped over to the lean side and stayed there!! it usually does this when my engine bay is hot...but usually jumps right back to rich when i give it gas. this time when i gave it gas, it stuck on the lean side...and stayed there till i floored it 
checked my plugs and they were greyish/white. there's only a few things that i can think of that could possibly cause this: Hondata (it's tuned!), 3bar Map, O2 Sensor(bosch universal), or my RC 550's which are peak and hold.
Has anyone with hondata+3bar+bigger injectors ever had this problem?!? just wondering cause if you guys have, i'm gonna take it back to my tuner and see what he can figure out. i'm gonna also try changing out the fuel filter and see if that also helps. oh yeah, my fuel pressure is at 55psi too!!
