demo'ed the Edge for a couple weeks in my work truck and decided against buying it. The power gains were nice, but there were no mileage gains like I expected. Now for the problem: after removing the chip, my truck's engine light came on. After restarting a few times it still came one. There were no problems that I could perceive, still seemed to be the same power as pre-chip, no hesitations, no sputtering, etc. Drove it for a couple days hoping that it would clear up, and it didn't. Took it to the dealer today to have it checked out, and they tell me the fuel temperature sensor was showing a reading of -40 degrees celsius, which was throwing the code. Has anyone come across this before? The truck is going into the shop Saturday morning to get checked out, butr I'm wondering if there could be any correlation between this code being shown and having the juice installed and then uninstalled, or is this nothing more than a faulty sensor and the timing was just coincidental?
