Default 07 Silverado Brake warning light ABS light( Did a search)

I did a search and found some info. on this. The only problem is my truck has 15,462 miles on it and I doubt the ABS box is bad. My truck is an 07 Silverado W/ a 4.8
I put a cam, LT's and a stall and shift kit in the truck. I ran it at the track and on the 1-2 shift it would hesitate and the ABS light would come on. Now every time I leave in the truck about 4-5 min. later the ABS and brake light come on. It does this every time without fail. WTF.

Under the speedometer section of HPtuners, try setting he General VSS pulses per mile to 81684 ppm.

unless someone pinched a harness or wire putting the headers or shift kit on,
you need to get someone to read the codes,
99% of abs lights are for wheel speed sensors,
unless a wire was damaged it should be under warranty anyway, let GM fix it.
autozone etc will read the codes if you don't want to take it to the dealer.
