i have a 92 f 250 that has a 460 that runs mostly on propane but sometimes on gas. is it possible for me to instal a super chip or hyperteck programmer?

if it was one you could put in it,with 335000 on it would not recomend it.

I put a "Jet" chip in the EEC of my 1988 F-250 W/460 and really improved the throttle response time but didn't do squat for my mileages as advertised.

other wise you have to change out the brain or have reprogrammed, i spent some time researching and was to chicken to try and install a whole new programmable system.
