Engine/Transmission (1998.5 - 2002) P0237

I'm getting the P0237 code. I've changed the MAP sensor and the truck runs much better and is more responsive than it's ever been but the code came back. I've pulled all of the wires and cleaned them with contact cleaner and applied di-electric grease on the connections also. Could this be my comp causing issues? I'm debating pulling it off and sending it back to Edge so they can take a look at it. Might even have it upgraded to drag comp status for later usage. Any ideas?

I had same problem, replaced map sensor and soon as I hooked up boost fooler I was getting same code. I cleaned all ground connections and still got code. I kept clearing out code about 5 or 6 times and so far its been okay for the last month. Like yourself, truck was not responsive until I replaced map sensor and now it runs like it used to. Good Luck.
