-Delete the cat if emissions allows it
-Pull the middle leaf and cut off half a coil to lower the truck a few inches
-Upgrade all of the bushings to Energy Suspension urethane
-Buy the $12 Pitman arm rebuild kit on RockAuto.com to clean up steering slop
-If you lower the truck, delete the load sensing brake proportioning valve and install a manual proportioning valve
-Block off the EGR and plug the air pump if emissions allows it
-Delete the air cleaner preheater hose and thermostat
-Home Depot alcohol/water injection sprayer and advance timing a bit
-Home Depot sound deaden the entire cab, doors, firewall, roof
-Upgrade the clutch
