Default Aftermath of gear install...

Just picked up my truck from a very reputable 4x4 shop after a new set of 4.10's in my 10bolt. It seemed like a great job until about 3 miles down the road. Now my emergency brake light stays on and my ABS light is on... WTH! Im sure the e brake is just in need of adjustment but what about the abs light? Maybe a wheel sensor has some trash on it or something? No clue.... I also have a terrible tune but now it seems more evident with the new gears, like wanting to almost stall while in drive while at a light. Being that it has steeper gears should it want to push through the brakes more than with the stock gears?

It thinks the front tires are goin faster than the rear tires with the output shaft turning more than the front tire pulses from the ABS...


It will also do that when you break an output shaft

If your ABS light is on then your regular brake light will come on.
