It'll get better with sticky tires. You can't really judge the converter if you're spinning. My 1/8 mile runs with the stock converter and Nitto 555Rs were in the 8.8 to 9.0 second range. My best ET then was 8.897 with a 2.05 60'. It was hooking good that day. With an Edge 3000 converter, my ETs were like 9.1 to 9.2. I was dissappointed too. I could not keep the tires from spinning. I got a pair of 26x10.50x15 MT ET Streets and went at it again. With the converter and the slicks, I was able to clock an 8.641 second run at 79.97 mph with 1.91 60'. Two other runs that day were in the low 8.7x seconds. That's 0.256 off my 1/8 mile ET and I don't have to worry about the launch. Just punch it from an idle and let the car do the rest.
