I have a stock 5.3 2011 sierra and am putting catless long tube headers on soon. I am wondering what I should be tuning for once they go on. Should I leave any of the o2 sensors enabled? Any tuning tips for the best performance with long tube headers?
I don't even really know where to start on tuning for them.
Thanks!
If you have to ask that you are not ready to start tuning anything. You don't understand the whole concept EFI tuning involves. Sorry.Originally Posted by naterosalez
Post your tune and a datalog. Then get ready to start learning.
Thanks. Will do when I get them on in a week or 2, just wanted to try and get familiar with what I need to do
Ive done all the basic engine tuning for stock. Disabled dod, smoothed out the throttle, changed some torque management, and tuned the trans. Just want to know what I should be changing specifically for long tube headers and any tips anyone has with their experiences.
Spark timing, Fueling with PE, burst knock, shift points, shift timing, tcc settings.
Posting your tune and a datalog then asking specific questions is the best way to learn.
Awesome thank you! You've helped a lot on multiple posts I've had.. Would it be okay to email you for more specific help once I get them on?
