i am looking for some opinions here, what kind of et will i be looking at with these mods and what is going to break?

the truck is a 99 1500 LT 4x4 extcab with 5.3, it ran a 16.7et(80deg day) stock in auto 4wd

only mod so far is the whipple kit, it included a k&n, and 160 stat, with the whipple it ran a 15.3et(80deg day) at 6.5lb boost

now for the planed mods this summer, it is a good list <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

ls1edit
headers(long tube ASM)
full duel exhaust without cats
2002 6.0(not the escalade)
converter(truck thruster 3000)
cooler day(60deg)
pully back up to at least 6.5lbs boost
other required parts(injecters? fuel pump? whatever is needed)

ok, what do ya think, what am i looking at for an et?

 

Cant say how fast you will go, but your rear end and transmision (transfer case) will have all they can take. Plan on replacing them soon after.

If you are going all out, you should look for ways to reduce weight and get lower gears. Run some skinnies up front. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
