I just bought a 94 Powerstroke. F350. 5 Spd. 4x4. Truck is pretty much all stock except I put on a K&N Filter/Intake/Intake Box. I Daily drive this truck plus will be towing alot with it. What is some good stuff to do to get a little more power out of her. I plan on doing a down pipe and exhaust. I also thought about the Edge EZ. Any suggestions?
