Hello FSJ,
Check out a couple of recent threads on the same subject (e.g., cold air intake, exhaust system, NO2, throttle body spacer, etc.). Add to the lists:
-- replace clutch cooling fan with electric fan(s)
-- replace belt driven accessory pulleys with larger diameter ones
-- get cover for pickup tray or remove tailgate
-- "rake" the truck (lower front suspension than rear)
-- remove unnecessary weight (unneeded tools, sand bags/cinder blocks, etc.)
Good luck!
