Check Engine/Low Power
Well, my check engine light came on this morning, and the truck has lost a lot of power. I drove it about 15 miles this morning and it acted normal, turned it off for about 3 or 4 minutes, and started it again and the light came on & power dropped. It still runs OK, will do highway speeds, but drives almost like it's on stock power. Turbo won't boost up much, goes to about 15 psi. What steps should I take to try to figure it out?

Checked for codes at Autozone, got P0237. Sprayed some WD40 in the MAP sensor plug and the other plug that the V5 uses. Hope that helps it, haven't tested it yet. When I stomp on it, it tries to get up and go, but kind of stutters and then bogs down. Don't know why it would start doing that all of a sudden. Hope the VanAaken isn't going bad.

P0237 is MAP sensor voltage too low. Have the code cleared, and try running without the VanAaken. Might just be a bad MAP sensor, or it might be a short in the wiring.
