Idle is in mid 14's, every once in a while jumps over to lean (again, I've been told thats correct), WOT below 5700RPM is a steady 13.8-14.0 in any gear.

Kinda like how the D16Z6 headgasket and the D16Y8 headgasket are now the same part and part number because they both work for the same application, but one was different from the other back when they came out.

Re: Running Lean, nearly stock, wtf.
I’m not very good at this stuff but is you have chanced your exhaust system. You are now flowing more air into your engine. You are using a stock ecm It dose not know about the change and is still using the same fuel maps. So same fuel + more air = lean. At lower rpms, cursing the system is using short/long term fuel trim and trimming you to 14.7 ish.
I can also see a misfire causing a lean condition. Ok I will probably get burned now by the og's.

the intake should have NO effect on how lean/rich I'm running since honda's are MAP cars, the ECU should be taking care of it.
