subbie racer

took it to a shop, they hooked it up to the machine and it says no signal and they asked if any work was done and i told them the last owner put 3.73 gears inside, they think its why my ABS isnt working and was told to get a tune to fix it


i already replaced the ABS module thinking it would work but i have no idea what else to try other than the tuning, it would be tuned by Proven Powers down in tampa, florida and they will be using HP tuners

$460 with dyno time
