If your up in Lubbock, I believe TSP is up there, and could do an in person tune for you. I'm sure you would rather stick will Nelson since you already got a tune from him though. Just an option if you keep having troubles.

Oh, you need to fix this! You can't have the hose going from the pass valve cover to the TB or it will pressurize the motor when you get into boost. Cap the TB port and put a small filter from Auto Zone on that hose. Also, make sure you have the check valve type PCV valve on the drivers side and not the orifice type.

also, does anyone know what it means when the codes are present in the computer, but the actual check engine light doesn't come on?

on my A/F gauge, what numbers are safe as far as the richness I should see at WOT? (still haven't gone WOT throttle yet..). When I give it about half throttle I see a value in the low 13's. I have an aeroforce interceptor A/F gauge input so I don't have the nice colorful lights to simplify it
