If you take your car to the dyno and know **for a fact** that there will be no abs sensor problems, why not tell the dyno guys that you will release them from liability and to go ahead and disconnect the front wheel roller?
How can you say the dyno is bad when it was the mode it was operated in that cause the low readings?
I don't work there either..
All it will do is flash the light, that is all.. Shut the car off and go for a drive, the light will not come back on..

I'm very curious.. How EXACTLY will an ABS light slow the rear wheels..? For the reason it would come on during a dyno pull, is what lilspic said.. The rear tires are moving and the front arent.. In no way, shape or form is that cause to "activate" or drag the rear brakes.. The only thing it means is that a wheel speed sensor (the front) are reading 0MPH, as the rear are reading ***MPH, meaning, you wont have ABS when you hit the brakes next time..
Do you work for them..? I really hope not..
