not to bad I see some stock trucks running 15.6 to 15.4 so you are close to normal.

 

I think those are excellent times for stock. My truck being a 4x4 only did it in 16.1 stock.

I think you are right where you should be.

Generally you wont see many ext.cab 5.3Ls running below 15.5 unless they reduced weight OR catch a really good DA.

 

Not bad, need to work on those r/t times little, no more sleeping!! Is it a 4x4?

 

yea I have just seen a few state they run around 15.5 or so, I how ever only hit a 15.9 stock.

 

I wasnt sleeping... I was working on trying to get the truck to launch right. different from a car.
and no, its not 4X4

 

I have seen R/T alot worse

 

Hey man you get to 70 in half a second longer than I get to 60..... and I have a modded 5.3L stepside.

I hate my truck! But hey, good times man!

 

Good times

 

with all the free mods done, you might be able to hit mid to lows 15's
