Jay I ended up with my launch rpm set at 8750 and the max set at 14000 leaving on the last red I would normally get a .5200 light or reaction time for though new to drag racing. .5000 is a perfect light. was running my normal 13.5 @ 96 to 97 mph. In the first round of eliminations I red lighted with a .4999 light. missed it by 1 10000 of a sec. I think i invented a few new swear word on my way back down the return road. Oh well thats racing.
