Have this programmer installed on my 2005 F150 4.6 4.88 gears, 9.75 diff, on 35s. With the programmer plugged in the ABS dash light comes on and stays on. Even stays on once Edge is unplugged. Only method to have ABS light turn off is go flash the truck module. While the Edge is plugged in the speedo works but is off by 5-15km/h depending on actual speed. The Edge speedo is basically accurate. Once the Edge is unplugged the truck speedo does not work at all. The speedo needle stays limp at the bottom and does not register a speed. Have the Edge unplugged to keep ABS light from coming and staying on.

Any assistance on this problem would be helpful. Heard that 5 Star can delete the programs on the generic Edge I have and install better programming. Is this correct?
