Default what does the star wheel affect?

the star wheel is pre boost fuel right? so if my wheel is turned all the way and i turn it back some it will help with egt and mpg? does it do any thing for after the turbo?

Ya, its a plug, just pop that little guy off, and turn the star wheel, which looks like a drum brake adjuster twards the engine for more pre boost fuel, and twards the fender for less pre boost fuel. I know if you have too much fuel down low the truck will bog, and smoke like a train, so you need to figure out if you like to smoke ppl out, or get a jump off the line.

your wheel has been turned to far, just take the afc off and flip it upsidedown, you can see it from there and get it back into the hole. no bid deal
