New to the POWERSTROKE world, so what are the advantages of doing a foil delete? Recently bought a 2001 F350 7.3 6SPD manual with 4.10s. Only 116,000 miles. Have read many threads in this forum and became a member, with all the knowledge on this site I will regain my investment for the membership cost. Have a new grey CPS in the glove box, what else should I keep in the truck?
