Moved to Tuning section.
You can look in the Tune Library and see if there's something there. https://www.duramaxdiesels.com/forum/forums/tune-library.31/
You could always ask Mark if he'd tune your truck, too.
Keep in mind that whatever LB7 tune you use, you'll have to rescale the FPR table to the LBZ values, otherwise it'll lope.

The hard part is just about any tune file you're able to purchase is going to be locked for edit to protect their IP/income (can't blame them). Your best bet would be to ask mark if he'd tune the truck or you can look at the various timing calculators/fueling calculators etc on this site and build your own file using the LBZ FPR tables.
thank you ! i have a communications issue now ill go to the tunes section nd research it .
Best thing you can do is research research research! This site has alot of good info in years 2007-2010ish. After that info started to get hard to find from the pros. I learned ALOT by doing just that. No one will sell you a tune to build from. Good luck and have fun!
I posted the values needed to run an LBZ regulator in an LB7 or LLY before. It’s an old post, but the numbers shouldn’t have changed unless efilive did something different with the scaling in that table. https://www.duramaxdiesels.com/forum/threads/help-cp3-issues.39652/page-2#post-575669
Thank you ! Got them . I’ll start with a stock tune. I have to buy one of those the guy who I paid 550 dollars to for 5 tunes in 2018 won’t put my ECM back to stock. We had a falling out . Tried to go from a 2700 quote to a 4800 overnight. This is after having my truck fir a month and a half and not touching it ! He gives tuners a bad name . Not only are the four tunes worthless now but I can’t even use my stick tune . Unless there is some way of doing that ?
Moved those two posts from the CP3 thread (josh's FPR values) into this thread to maintain continuity.
Did you ever get a stock tune since you can't use yours? If you need one, I'll email you one to play with. Or if you want a solid base all around dsp5 to modify and learn on your own then ill hook you up.
So much I don’t know where to start ! About killed me but got the truck put back together. .hired three different mechanics to help . All three quit after getting paid the first and only time ! No one wants to work anymore. My original motor had 70%unleaded ran through it . Was detonating bad then quit and it never ran again . Had a motor built took over two months and ended up getting screwed over on it . Upon start up after several heat cycles measured with a thermal gun . Looked for leaks ,checked all fluids . Drove it for several days and monitoring it I noticed antifreeze was disappearing from the rad overflow. and intermittent codes as well .The fuse holder for the gear indicator power circuit was loose . And much to my dismay it was eating antifreeze not leaking anywhere.
