Hi everyone,

Just got a 2000 GMC Sierra about a month ago and ran accross this forum.
It is a very informative place and thanks for all the posts on mods.
My truck is a Z71 4x4 RC Sports side bed 5.3 Auto with 410 gears.
My question is what 1/4 mile ET's could I expect with stock airbox,
K&N air filter, 160 degree Thermostat, Hypertech programmer and aftermarket
Cat back exhaust. I don't have a bunch of cash to put into mods.
The only mod I have done is the K&N airfilter, so far.
Want to keep truck as a daily driver, and will use on long trips in summer.
Thank you

I would have to say low 16's high 15's. Launch in 4wd hi. Those 4.10 with 4 wheel drive wheel put a kick in your pants. Also you can do so many mods to these and still use them as a daily driver. theirs multiple people running these trucks into the 12's and drive them everyday in traffic and the country.

 

i'd say 15.5 to 15.8. it should hook just fine in 2wd.

 

with just the air filter, expect mid 15's

with programmer and exhaust probably low 15's

with my setup (minus Eaton and Yank3000) i run about 15.6 but that is for an EC

 

A friend has a 1998 Dakota RT 360 with K&N intake. Only mod he has. I want to be able to beat him, we have not yet raced but will this spring. Hope to smoke him.
Thanks

 

you should. get a custom tune. that will help alot.
