Working on a tune for my own '11 GMC Yukon 6.2; I have attached the file for any pointers or basic recommendations after review. Vehicle is stock other than CAI/Cat Back Exhaust/Cats Gutted due to prior problem.
Thanks!

Logs will help too, so that we can see how it runs with the changes you made.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I just did a couple revisions tonight and have not logged it again yet with the changes. I will load it up tomorrow.
Anything you prefer to be added to the log?
It's got a lot of timing in it for a truck, hopefully you run good gas. Your low octane table though.... If it ever finds it's way there it's going to fall on it's face under acceleration... "Usually" you copy your high octable and paste in to the low, then subtract like 8 degrees from it. Some people do more, some do less. When you log it make sure knock retard is in there.
I have a 2010 yukon Denali so I'm not speaking from theory. Whatever that's worth, or not... lol

Look at your transmission for sure.. TC slip especially and NO Lockup in 1-3 gears for sure.
I have a 2014 with some mods. but this is the minimum for a stockish yukon/truck.
Yes absolutely this.Originally Posted by Tfoggy
Can you elaborate a bit more on the transmission settings? I'm interested in doing this.
So, on my previous log with this timing map, there was no knock retard...log was done with normal driving, highway and a couple good pulls. I do run 93 octane gas.
I also just tweaked my low octane table...thanks for that.
As for the transmission settings, do you have a screen shot you can share?
