2010 5.3L/6spd CC 2wd - Nelson Performance Improvement 1/4 mile

its a crew cab if youre going to run it, run it as it sits on the street. a rcsb is made for racing others are just to haul ppl there . as for shifting it, having a tune rids the use of shifting it. i noticed the pcm learned the paddle shifting on the 2nd pass so thats a washout there.

Ran a 15.017 @ 92.81 mph Friday night.

Pretty sure it had a 14.8x or 14.9x in her, the track was crowded so I only got to run 3 times.

Spun the tires really bad on one of them so really only got 2 passes in.

I'm going back a couple times before the Tru-Trac and 4.11s go in so I will post some more updates.

so headers and cut out netted you a gain of 4mph? thats pretty impressive and congrats on the latest improvements

Thanks.

Yeah the headers and cut out got me to the finish line 6 tenths quicker and 4 mph faster.

I'm going to try and get back in the next few weeks, before NP installs the Tru Trac and 4.11s to try and dip into the 14s.

EDIT: Also I'm going to try and get my truck weighed this week just so I know where I stand in regards to all my race buddies RCSBs and ECSBs.

Here is the time slip, I was car 60 and BB was a buddy of mine, he spun at the line and I was right on his RCSBs rear fender the whole race, fun times!

Nelson installed my gears and tru-trac the last week and also did a re-tune, now that they are all broken in I'm starting to play with the truck some.

Today I did some WOT pulls and I will be surprised if I don't see some significant gains from the swap, I mean my truck is much, much quicker now.

I was out showing a few buddies this afternoon and they add about 500 lbs of weight to the truck and it still pulls faster and harder than before.

I am taking her to the track on the 18th to see where she is at now...update coming soon.
