Joe, a loose race converter is usually close to 25%. Stock converter street cars is usually around 20%. Fluid temps have an influence on slippage, so several pulls close together often shows a drop in power as more pulls are made.
The knurl on the rollers is hard on your slicks. If you don't have street tires you could put on it, I would put 25 or 30 psi in the slicks. Use old ones if you have to. Start low as you can in high gear. Converter flash will make your torque look killer! LOL
