Need help tuning my gen3 6.0 ls

[Dawson_Champy]

Very new to the whole tuning scene, just installed a btr stage 2 truck cam kit into my truck along with rebuilding the motor doing things such as main, crank, camshaft bearings, new rings. Im looking to tune the truck for daily driving/occasional towing but basically an all-around tune to have some fun but not push my motor too far. Also installed a 2400-2800 stall torque convertor, running all other stock components including intake and exhaust. the truck is stock height on 35x12.5.
Havent changed anything yet just have a stock file. I am tuning using HP tuners.
Intake [email protected]: 262
exhaust duration @.006: 268
NET lift for intake and exhaust 0.553"
anything and everything is appreciated!!!
Thank you for your time!

Help as in give you some Youtoob links, or Help as in tell you what to change, or Help as in hire somebody to remote tune it for you?

(I only recently figured out that some of the difficulties between myself and my mother is that when she says 'help me do X' what she really means is 'just do it for me while I sit on the couch' but she doesn't say that, because saying that out loud would be rude.)

Do you expect tuning to be an ongoing hobby? If not hire one of the professional remote tuners on here to do it.

I'm hoping to do some more tuning after this however I am considering hiring a professional for now to get me back on the road and going through the files to understand what was changed. I have multiple projects and would love to learn. I have set my basic tuning to get me started on a baseline by bumping up my idle for operating temp along with rolling idle 200 rpm. Ive added 30% to my idle airflow table and changed my cylinder mass from .08-.28 in the range of 0-800 rpm up to 20 replacing the original 16 to at least get me going.

that will get you rolling but going WOT won't be safe.

Then you'll want to research idle spark timing over and under run.

Then you'll want to figure out how to misfire counters from the cam.

Then go over to goat rope garage and watch videos on how to use VCM scanner (and spend the 5 bucks for his layouts)

Then some videos/forum posts on idle LTIT tuning

Then how to use your narrow band o2s to tune your MAF, then how to tune VE.

Then buy a wide band o2 and tie it in to VCM and tune your MAF, then VE for WOT and power enrichment.

Then figure out how to safely adjust torque management and adjust the trans tune some.


Here is a log of my path, missed some of early work before I found the spot to put notes about the tune. I also did some HP tuners work on my LS swapped Jeep, so I kind of knew my way around HP Tuners. Going on 2 months trying to dial in my truck and I am just getting to the spark part of the adventure. As a hobby it has been fun but it is a lot of work to understand everything to do a correct tune. I'd assume for most of it is a waste of time if they aren't looking to be a tuner. Cheaper to pay a pro verse the number of hours you'll spend learning it. Looking through the "new posts" tonight it is pretty much an endless amount of folks looking for a free tune. I think a lot of the long time turners are jaded and reply with a smart arse replies, probably would be more successful in explaining the amount of work and knowledge required for a tune and folks probably want to be paid. I'd assume most ignorant folks don't understand they are crossing the line by asking for a free tune verse tips on how to DIY. Good luck!
