do you have a pyrometer installed to monitor egt's? if not DO NOT touch the fuel screw. other than that you friend is right. take that triangle plate off of the passenger side of the IP and find the 5/32" allen head screw. turn that one flat of the allen wrench at a time. test drive the truck after each adjustment. what the pyro if you have one.

With the thermocoupler in the exhaust manifold you dont want to run temps 1200*F or greater for extended amounts of time. You can go higher, but need to limit the time. This is due to the fact that the pistons are aluminum and aluminum melts at 1200*F.
