He had a 3" intake that went right behind his headlight, then it went to 2.5" to right behind his bumper lights.

I'm thinking there was some sort of restriction and the engine wasn't breathing enough up top. That, or 3" and that long piping is too much for a stock f22? I don't know, but problem solved and it's running like a healthy stock f22. lol

Intake turbulence perhaps? weird.

You know that bottom skid shield that goes under your fender? I guess his piping was touching it and I guess after 5k the engine was sucking enough to suck the plastic so the plastic was now blocking air.

That's the answer that makes the most sense right now. That part of the skid plate is pretty flimsy on accords, so yeah.
