From looking under the hood, looks like all you have is a cold air intake. I see stock fan shroud so there probably is not much done to it mechanically. Otherwise, you would see electric fans at least. Maybe a mild tune?
Yeah. That's my guess. Tune for sure.My problem is the ecm has been "locked" requiring a code. It is running with Kooks headers, no cats with 3" pipe back to MF muffler. So they deleted the O2 downstream sensors. They will not reset. I live in TX and they must show "ready" status on emissions test to pass. This truck came from Michigan which is not required from my understanding. Trying to determine if there is a way to access the ecm to make the necessary changes. So far no luck.
