Default Have a problem with ABS

Well here is the story on my abs light that keeps turning on when i launch my truck sometimes and it really bothering me. Would really like some answers on why it keeps coming on. I just installed a Procharger on my truck and i have a thunder racing custom cam kit with double springs and hardended pushrods and arp head studs, upgraded head gaskets and a yank 3000 stall. Just installed some tr6 spark plugs and taylor 10.4 spark plug wires. Still havent tuned the truck for the procharger but even before i had the procharger the abs light would flash and stay on for a while. Its really getting annoying and would like to see what you all thought of the problem. If anyone can let me know whats up just post and i will see.

how many miles on your truck?

maybe a wheelspeed sensor going bad? most abs problems i've seen have been sensor related...

melted a wire on the harness by the frame/exhaust/brake booster?

over time the sensor will get brake dust on it no matter the mileage. you didnt change gears did you?

Have you figured out this problem? I just installed a 3k stall and when I launch it hard, it'll spin the tires for a second and then the ABS light will stay on for a while. Doesn't seem to affect anything, although I haven't tried to slam on the brakes to see if ABS works.

Crazy.

I used to have this problem, said service abs and stabilitrack system. When I swapped converters it hasnt came on since. Definatly a loose connection or sensor somewhere
