ABS/Traction Warning Light - Turbo Build
 

My turbo produces about 400 ft lb torque. Under hard acceleration, ABS/Trac lights switch on and stay on until I turn off the car.

I have KW 3+ coilovers, Cusco stablizers and Advan Neova AD08R 225/45 R 17 (front) 255/40 R 17 (rear). The same happens with my winter tires (225/45 R 17 on all four wheels).

I do not notice any wheel slip when the lights turn on.

Can anyone tell me whether ABS and traction control are off after the lights turned on? My Subaru dealer claims that ABS/traction control are still working and, therefore, I should not worry.

Has anyone a high hp build and does not experience this issue?

Thanks!
