nice times bro

 

<Actually our NNBS are more heavier than older 06- models/ but our engines have more potential in Power/ you prob have 243/799 heads..

4.10+ 3600 stall/ should get you moving off the line.pretty fast. 1.90 @ 60ft atleast/

i think ur tune is way off*

 

What times do you run? And what size engine do you have. you have a RCSB and mods.

 

i hit 14.2 with just a cam(hot cam) that cam sucks for track it's meant for top End/ + tune / i dont have a stall , i hit 2.09 on my 60ft/

on 5.3/ its not much different between 4.8/5.3 on these nnbs/ friends of mine running 4.8's are running low 14.s' on same setups'

 

So you have a 5.3 with a cam? I assume you are running smaller tires at the track.

 

sorry to tell u guys but i was running 14.2 with just a wheatley tune and a intake no headers just a muffler ,

with a 3.42 gear ..... and i have vids to prove it then i had LT headers w/stock cats and i went a 13.9


the tune on that truck is WAYYYYY off ... even for a 4.8 it should have done better than that

 

I guarantee that it's closer than your mail order tune. This truck ran mid 16s with a CAI, and catback. I bet yours would have done a little better than that stock too.

 

I started a thread for the NNBS trucks track times so everyone tell all these 13 second bolt on 4.8 nnbs trucks to post instead of comparing my 4.8 to your 5.3 or a lighter truck that weighs 300+ less than mine on small 26' tall tires when I did my runs on 20's. I bet you guys would think someone comparing there 6.0l to your 5.3 would be an idiot.

4.8's do not make the tq that a 5.3 does period. I put a 2500 pi converter in a 05 silverado with LT and a tune it ran 9.06 in the 1/8. he 60ed 1.90's on radials and stock 17's

 

im not hurtin at all buddy, when i get headers, change up the intake a lil and a retune, it will put me in high 13s

 

Boooooo/ 4.8 dude got offended.. lol< j/k were just triying 2 help you out... im sure ur 4.8 has more potential performance wise...

i did run with 20's also..
