    Check out thedieselplace com 6.5L section if you haven't already. There will be plenty of reading and suggestions there.

    Be sure to relocate your PMD, buy the harness off ebay and run it somewhere cooler.

    i had the 4 inch exhaust from ss and the reflashed ecm , new pmd ,wastegate controller and new injectors from heath......the truck ran like a raped ape , kinda :laugh: its was still a 6.5 but it went a lot better then before , put it this way from a dead stop truck stomp on the gas and it would burn tires something it would never do before

    I have had buddies mount them inside the cab with a small computer fan set up to blow on them. Works out great

    have them put a aftermarket Pmd kit on it .It has a longer cord .a heatsink machined aluminum billet with cooling fins . it monts on top of the intake cowl .the facory pmd set way down by the pump .get hot and burn out.
