I recently bought a 2000 f-350 with a 7.3l engine and an automatic transmission. I am looking to chip it for better fuel mileage and power and I am looking for some advice on which programmers are the best for this truck. Any suggestions?

Every rancher I know who has changed the chip in their F-350, with the 7.3L engine, has not been satisfied. They wish they'd saved their money and left well-enough alone.

I work for a ford store and we always use Banks or Bully dog as an aftermarket option for a chip. They seem to work the best.
