I have an 07 NBS Vmax and I just popped a 6" fabtech performance lift and swapped the gears to 4.56. I alsop added 35's on 20's. I made adjustments in my tune to account for all of these changes but the damn ABS light keeps coming on. My dealer says they cannot adjust the settings in the ABS for the NBS trucks. Is he full of it or is this true? Just wondering what I should do next. Thanks for the help!

I have no clue. Have you tried calling Fabtech?

if your tires are not the same size size all the way around your ABS and Brake light will come on. you can tune for different tire sizes on front and back though. just some more ifno.

is it nnbs..
the light is on for a reason, the dealer or a shop with an up to date scanner can read the codes to tell you why it is on.
could be damaged sensor or harness problem, or a plug not re-connected properly.
need to read the codes...
