why dont you tell us your vehicle and we can give you an estimated ET.....

 

03 ecsb z71 5350lbs. with me in it
TR220/112 LT's, ORY, cutout, CAI, street tuned with a wideband, a little tranny work nothin major (stock stall) 3.73 gears
IDC's are at 103% and my o2's are not switching right so my fuel trims are a little off now due to the o2's not heating up enough 6-8% rich on the trims now
need to get new injectors and o2's they have 65k on them

 

stock stall is gonna hurt you.... but id say high 13s... or 14.0

 

you must be high...lol
maybe a high 14 at best this is extended cab 4wd not a rcsb 2wd

 

i went 14.8 with a 3000 stalled 4.8 with headers and 4.10 gears in a EXT cab 2wd...

so if a cammed 5.3 cant hit 14.0 id be mad...

 

I am in Louisiana though..... sea level....

 

it definitely doesnt run anywhere close to 14.0 its just to damn big and heavy
SW MI here Gtech said 15.2 with a buddy in the truck...that may not be right though it's had some calibration issues

 

hmm.. how much heavier is a 4wd to a 2wd?

 

good question, I would have to say somewhere around 400lbs. plus or minus 100lbs.?

 

if your tunning is good and you get traction (not sure if your gonna launch in 4wd or not) i would say 14.5. Back when i had a 5.3 ccsb 4x4, efans, cold air, and tune i rand a 15.4. Thats no cam, lts etc, and even heavier. Keep us posted tho for sure.

btw any sound clips?
