So, i just got hptuners, and want to mess with my stock 2015 5.3 sierra. What should i adjust and how much should i? Where are some good files and good literature on tuning the gen v 6l80? I?ve figured out how to delete dod and the speed limiter, its just so over whelming. Thanks
Yes it does seem overwhelming at first. I just got HPT around Christmas. You can pick it up fast, just work on one thing at a time. I also worked on the trans in my 2015 Silverado first and it will make a ton of difference in the drivability. A few videos I found extremely helpful:
Some torque management help: https://www.youtube.com/watch?v=M8X5z0qxnM4
Download the BlueCat trans calculator, this will make things very easy as a start : https://www.youtube.com/watch?v=X8vi7A7RGEs

This will get you started and make a big difference. I am still playing with shift pressures and timing honing in on what I like. Start with these changes using the BC trans calculator and the other changes in the videos. I ended up pulling back just a bit on the shift timing, as I felt like on a stock truck the shifts were stretched out a bit too far. I also did not go as far on the oncoming pressure presets or line pressure as Cesar mentions. I am in the 300/450/550 range right now on the oncoming presets and shifts are pretty firm but not bone jarring, and around 850KPA line pressure. Once you get started it's fun to play and see what the changes do.
Also look up my thread on Driver Demand tables, that makes a world of difference on these trucks!
For what it's worth I pretty much never touch anything torque mngt related for the transmission and never have a one single problem with performance. I do not suggest changing much of anything TM related for now.
Most of the stuff I do is stock or lightly modded.
Thanks fellas! Im going to tweak the file on lunch
Wheres the oncoming oressure oresets?
Forgive me, I havent used forum’s in years just fb groups lol
The reason you are having a problem getting an answer is because the question is so generic. Like asking "How do you fix stuff"?Quote:

It would help to have a reasonable understanding of how engines, and transmissions work to begin with. Then you will better understand what the outcome of changing something will do. The newer you are to tuning the more you want to go step by step and don't make more than one change or you will get lost and have to revert back to an original file. Also it helps that each change you label accurately on what you did and what step you are on.
It's a spammer. Check out that weird underscore in the quoted text that doesn't exist in the original. I hope everyone responsible for shit like that dies in a fire.
I couldn't agree more with that statement.Quote:
