superchips reprogrammer
I reprogrammed my PU ('03 F350 SC 8' V10) last week and have to report it works great. It was easy for even me to install. I set it on the 87 octane program, but edited the shift points to one mark above stock ( I guess this would be 2.5 mph.). The trans is now perfect, the engine sounds better and you can feel the increase in power. I made a road trip and got 14.2 mpg. Considering I had to check the shift points a couple times, this is at least the same as before. It shifts at 5000rpm, but if you let up to shift it earlier, it doesn't downshift when you nail it again. At 70 mph, the gas pedal is about half as far down.
