Somewhat tricky install - ended up wiping out my PCM relay during the install somehow. But once installed... Awesome chip, The 100 hp setting is pretty intense. Installed in a 7.3 l 2001 Ford F250.
Great power for the money

This is the first modification to my 2000 F250 7.3L; everything else is stock. Increase in power is remarkable, the chip seems to wake the engine up. Mileage increased by 1-2mpg under moderately aggressive driving in the +75hp setting. It takes some increased attention while driving to avoid over-fueling: the chip dumps in more fuel than the engine can burn if the pedal is to the floor before the turbo can wind up (especially in the 100hp setting). Power is good under these conditions, but it results in lots of black smoke out the exhaust. It seems like air intake and exhaust upgrades will compliment this chip very well; the 100hp setting is really not useful without further upgrades. One minor complaint: the threads that secure the switch to the dash are soft plastic and are easily stripped (everything else seems durable and well-made). Be careful of this during installation. Overall I'm very satisfied - this is the best money I've ever spent on a vehicle upgrade.
