Hi,
I have a 2001 5.3 Lt silverado and i have alot of questions regarding chipset, programmers and tuning..

also if you have specs i'd love to see them por favor..

1. Which is better programmer or tune
2. which is cheaper..
3. how can i over ride my o2 sensors..
4. which is better to help with shift patterns and what..

 

your best bet will be a computer tune from one of the sponsors on here (i.e. wheatley, nelson, blackbear, etc.)

 

Welcome get a tune not a programer.

 

Welcome, I agree get a custom tune.

 

Custom tune from a sponsor ftw!

 

i take it it's completely worth it.. so how does it work for the tune.. i mean with out going in to a place to have it done.. and about how much will it cost?

thx

 

you can do a mail order tune

and they are usually around $300
