I ran a 15.0 @ 90mph. This was in my wife's '01 Ext Cab 4.8 Sierra with the following mods:

UPD intake
ls1 electric fans
ASP pullies
HP tuners
Magnaflow exhaust

I am pretty happy with the results. I whished I would have dipped into the high 14's.

 

Damn!

 

What gears does it have?

 

3.73:1

 

those are some pretty good times for ec truck. nice

 

Great time File.

 

Seems like a really good et with those mods,even with 3.73s. It would be interesting (but probably impossible) to know the gain from each mod. Maybe it's a little bit of a factory freak.

 

Man thats quick! Thats about what mine runs, maybe quicker.

 

Tib that is pretty good man. i have ec step side with a lot more done to it and i can't seem to break the 14.8 mark. here lately all i can get is 15.0 even. i think my truck is working backwards. more mods equal slower time. lol

 

That's about where my truck was with similar mods. MPH seems to be pretty good too! Congrats to you and the wifey!
