"Quick delivery, 10 minute review of instructions, 10 minute plug in to reprogram. Went from 13.4mpg on the highway to 16.7mpg highway. Set it to 87 octane, set my tires to the proper setting and was off and running. Jump in response time, horsepower and over all feel of the shifting in my Expedition (5.4L). One annoying thing is I can't get the internet updates to work even after hotwiring my router. Called the help line on an initial error code and they took care of it right away. Overall, very pleased and wish I had done this years ago. Also is complimented by an Air Intake system like Air Raid etc. Buy it and then just try and keep your foot out of the gas!!" —Douglas L L from Bellevue, NE bought a Superchips Flashpaq Tuner for a 2004 Ford Expedition.
