need help diagnosing!!!
All of a sudden my cars running super lean only when I get into boost.I've put a new o2 in it,no exhaust leaks,boost and vacuum has not been affected.new fuel filter,fuel pressure is at 60 psi running.can the maf read wrong with out throwing a code? What about the back o2? I'm at a loss.

Have yet to figure it out.triple checked for vacuum leaks.guess its time to throw parts at it.I'm going to try maf and map 1st.if not it then oh well then it has new sensors.just makes no sense.I deleted the evap for a couple pulls and no change.

I would think if it was injector,it would do it even cruising.I don't know.I'm going to go over everything again to make sure I didn't miss anything.
