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.Quote:

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?Quote:
