I can clear the code and it will come right back as soon as I cycle the ignition. Vane is working and the truck hauls ass. Idles perfect on my rumble tunes...

I've checked for loose couplers, cleaned mafs, and it's tight.

Data logs show nothing out of the ordinary...

All mods have been done in past month. 2005 with 115k miles

Mods:
Efi live Kory Willis tunes
LBZ mouthpiece
Pro fab intake with stock box
EGR BLOCKED
Mbrp downpipe and exhaust
PCV RERUTED

HELP!!

Did he check the tune or just the MAF?

Did you ever find out what was causing your code. I have an 05 lly with the same thing going on. Its been an ongoing matter. It doesn't really seem to affect performance but the code is there and comes and goes. It started after I added the efi live. I tried everything and my tuner adjusted things and the code is there no matter what when running the tunes. with the stock turbo and the stock read the code is gone. I even changed out the turbo with the danville 4094 and it still throws the code. Not to concerned because it really doesn't seem to affect performance but it is annoying when the engine light comes on. Was wondering if you ever came up with anything.
