Everytime I install my Ppe tuner, after driving it maybe half a mile my ABS light, Brake light come on and I get a message an my dashboard saying Service Brake System. I cant figure out what Im doing wrong I set the proper tire size, gear ratio and Im pulling the right fuses. Has anyone had the same problem? Any help is appreciated, Thanks!

IIRC, calibrating via tuner for a 35"+ tire will give you an intermittent ABS light problem. The only way around it is with a techII, or possibly (though IIRC you can't) EFI live.

^^^ Yeah I was actually thinking about lowering the size down to 35". Will do that today and let you guys know what happens. Thanks for the info guys!

Im not sure what a techII is, can anyone explain what that is?

You have to leave the programmer at 35 or it'll keep setting it off. Mine kept doing it till I measured my tire 37=35.5 so that's what I set mine at and it works fine with no problem.

So I set the Ppe at 36" for the tire size and everything worked out, my ABS light or Brake light did not turn on. Im going to try to raise the tire size little by little to try and calibrate it as accurate as I possibly can without setting the ABS or Brake light off.

The techII is gm's diagnostic computer. Your dealer will have one, or you may possibly be able to find a local shop that has one as well.
