Talking 12.48 @ 105.7

I went to the track tonight with my truck. Same setup as last weekend at Rudy's when I did 595/1220 on Dunbar's dyno. Tune was a standard 310 TCM file that you get with a level 4 license. No tweaks for my ported fuel rails. Best pass of the night was a 12.48@105.7. All of my passes were made on fuel. My truck doesn't have a nitrous setup and won't see one for a long time. I am extremely happy with the times I ran tonight. Had a couple in the 12.52-12.54 range and few 12.60's. Track conditions were ideal with temps being in the low 50's and high 40's. It seemed the colder it got, the worse off the track was though. It was about 52 degrees when I ran the 12.48 and once it dropped down in to the high to mid 40's, I couldn't get the truck to hook up as well.

Time slip looked like this....

60' - 1.672
330' - 5.003
1/8 - 7.860
MPH - 85.62
1000' - 10.359
1/4 - 12.486
MPH - 105.73

Wow, that is fast! I ran (literally, ran) the 100 meter in 11.1 seconds this week, but a 1/4 mile in 12.48 seconds! That is scootin'!

Tailgate off, spare off, receiver hitch off, and no more EGR coolers. Going by a few other trucks that have done the same, I should be right around 7900 lbs with me in the truck.

Congrats.

On another note...did the truck stop pulling at some point? The mph seems a bit low. Just wondering.

It's back halving 20 MPH, which is pretty consistent with most 6.4's with 3.73 gears and this size tire. RPM gets a little high before going through the traps. I need 3.55 gears pretty bad.
