I forgot that SC has an option to do a 1/4 mile datalog.

 

damn john. I want your old transmission in that case LOL

 

From those times he posted it looks like 0-60 should be about 6 flat.

 

just went a remeasured my tires, and checked in the SC. set at 33" right where it should be. also, i had TM set at 60%, gonna put that down to 20-25 see if it makes any difference.

 

Try between 8-12 percent tm. I got my best results in that range.

 

Well Done OlDirty, and like Teach said if your time to 61mph is any indication.
This only proves the Importance of Gearing and Transmission VB,TQ, etc modding, for which my Truck is lacking however gives me happy days to look forward to when I do get those done and like the Old Bull said to the young Bull I'm just gonna take my time and walk down there and screw em all.

 

heres a pic of the times from the superchips after that last run:



did another run, 0-60 logged. fudged up the launch pretty good, and spun the tires too much. you can tell by the drop in time. 6.34



i still dont think its right though. my truck shouldnt be THAT fast with the amount of mods i have.

 

do you have a GPS? You could use that to determine if your speedo is right. Awesome times for sure either way. Even if its off a little, its still a really good time considering you have a 3/4 ton truck.

 

John, well done! I turned two 6.40's using my AI gauge yesterday. And a odd 6.09 on my SC3865 that I couldn't backup. Data logging is great fun....

 

0-60 with s/c 91 Tune 6200 wot 1&2 shift and K&N 57 6.71 vs 7.11 w/o intake.
Hard to launch w/o tire spin but got it to. Trac ctrl destroy my time no lauch at all.
Now gonna see what happens when tuning tranny.
