ive got an 02 ecsb Z71 4wd 220/220 .581/.581 112 lsa,lt's,wheatley tune, circle d 3000 stall, stock tires 265/75/16 its got 3.73 gears tru trac just kinda wonderin what i should be runnin ran outta money so ive yet to get a cai so i know thats hurtin me thanks

 

If I had to guess, mid 14's, maybe low 14's. But lots of variables in there, elevation, weather, track prep, etc.

 

i'd say mid 14's as well. Depending on tires, you might get a low 14 outta it.

 

alright thanks i got some slicks just need to get them mounted i cant remember the size but there little my buddy said it should be like havein
4.10's just have to fix my fuel problem then maybe i'll be runnin those numbers

 

I think 13a

 

14.8-15.1
I would set a goal of a 14 anything but don't be supprised if you stay in the 15s.

 

i ran 15.40s bone stock 01 silverado 1500 2wd 5.3/4l60e with exhaust. with no spare or tailgate and headlight out. just for reference

 

well thats the shitty part i got a fuel problem cant get the fuel pressure i need,absolutely did everything everybody told me to do and a fuel pump regulator the whole 9 yards and ran a 15.41 pretty shitty nothin was consistant u could feel it sluggish the whole way down the track and never went over 90.24mph so i was pretty pissed cause everybody i talked to before i did this was sayin i should be in the mid to low 14's and with the slicks high high 13's

 

what pressure are you seeing at the rails?

the stock pump should be fine if thats what you have? so you got an external fuel pump?

 

gettin 44psi at the rail talked to a gm tech said i should be gettin between
58-60 its lean as f#ck when u pull the plug he said the pump should be pullin 8.8 amps when u cross the fuel pump relay and check it there and mines pullin 14.4 he said i have a bad ground but all my grounds are good and im on my second pump just cause maybe the first was bad idk its got everybody stumped
