ive got a 99 f 250 with the 5.4l 4x4 with 33.5" tires and i bought a superchips flashpaq to adjust the tire size but im getting a error code from superchips about my abs module. my ford tech friend told me it might be because its a non-reprogrammable abs module. any way around this so the transmission shifts correctly? and i want to try not to buy the jet performance "piggy back" rear axle thing to make the change, id rather use the obd 2. thanks in advance
