    so i had my 4.56 gears installed yesterday...it's very cool...but i guess i didn't realize that those gears would throw my ABS light to come on.

    My buddy told me that the speed sensors aren't registering at the same speed causing the ABS light to come on...i didn't know that...

    and from what i've been finding online, there is a programmer by Hypertech called Speedometer Calibrator...i have no experience with these programmers...and was just wondering if anyone has any input or other ideas...

    thanks in advance...as always...it is much appreciated. :glasses:

    Diablosport tuners can turn it off. As I have a custom tune (Diablew tune -- performed by @06MonteSS on this site) I had the 4.56 gear change rolled into my custom tune by Lew prior to havingthe work done, such that as soon as I picked up the truck I installed a new tune to avoid the idiot lights.

    Lew sells Diablosport equipment as well as custom tunes (and I believe he does bundles). Reach out to him if interested; he's great to deal with. I'm not on the payroll -- I'm just a very satisfied customer.
