The smoke screw is covered by a cap on the back side of the AFC. takes two screws to remove the cover.

In and this should help you... But all it will do it add fuel down low making egts hotter and possibly making it take longer to spool... Didn't mess with mine

More rack travel and yes loosened it up some but adjusted for full travel at 25 psi. When I get the truck on the track I may have to adjust it accordingly
