Well took my new truck last night its a 09 4 door 4x4 crew cab with a 6.2, 3.42 geats first pass ran a 15.09 at 92 2nd pass the air went to hell it went a 15 .20 I'm happy with that all it has done to it now is true duals with an x pipe plan on getting it tuned before long what do y'all think it might do on a good cool night?

 

I in the passed have gained as much as 3 or 4th with really good weather... Did you have a head or tail wind?

 

some tail wind not bad how much should cold air intake and tune pick it up

 

Tail winds are a good thing! Lol Not sure on the tune and the CAI... Someone will chime in on that. I hear a tune really wakes these things up

 

no bad my crew cab 5.3 went 15.3 tune only so a tune should wake up your truck alot.

 

are track times normally slower there than they are in south texas, cause my 07 4 door 6.0 ran a 15.0 bone stock and iv driven a new 6.2 and its definitely faster stock

 

tune will wake it up a lot. what muffler(s) are you running? are you running 3" duals or 2.5"? CAI will help but not a lot, it only helps when you modify it to actually suck in cooler air. when, IF, you o with LTs i recommend buying big. these motors love 1 7/8" with mods. im running 1 3/4" on my 6.2 and its starving up top. i just cant see spending 1500 on a 102mm intake, 1500 for 1 7/8" LTs, 500-600 exhaust work. for all that work id rather put a 150 shot on it to help with the top end.

the list id do if it was my truck.


Tune
LTs/OR-y
good flowing muffler depending what you have now
converter
cam
gears


also what'd you do with your stock exhaust? wanna sell it?

 

its got flowmasters 2 1/2 with x pipe the weather down here sucks humitdy is way high all the time all i plan on doing is cai and tune i would like to get a low 14 maybe high 13 might spray it one day dont know

 

your doing ok with dual 2.5" but itd pick up more with dual 3"

ruston is only 2hrs from me, i figured itd be cooler up there vs where im at by Baton Rouge

 

this past friday my friend and i took our trucks to the track. end result his 10' cc sb 6.2 3.42 2x4 went 14.25 only has a dynomax cat back. truck normially runs 14.6-7s. my 07 ec sb vmax 6.0 4.10 4x4 went 15.18 down from a 15.71 all i have is airaide tube and filter. air makes all the diff. (temp friday night was 40 deg and we were 80ft below sea level according to his air guage.) air conditions here in the summer are 90 to over 100 and equall humidity and density. octane is a factor to... just my input
