Okay well I am not dissapointed, but I still didnt get 15.xx. Reason being is I didnt launch great at all the first run and the second time I only wound her up to 5000 to see if I get better times. The first run I ran her up to 5500-5600 and got a better MPH, but had a 2.6 sixty foot because of being the first time on the 4.10s. Second run I had the best launch I have ever had 2.3 60 foot time and a .053 RT but I shifted at 5000 where theoretcally I should shift after looking at my dynos, but I always run slower when I do that so from now on its 5500 with my current set up and maybe 6500 once I get my top end built. What would be the best way to launch with the 4.10s and nitto 555s?
