03' Duramax CC/SB.
Im going to see if i can copy with my hptuner the hypertech 1 and 2 program I have on my LB7 and I may load in your econ tune to see how it compares as well. I just Joined today.
Just so you know if you are using HP Tuners to tune your Duramax, the Edge Insight PRO will work as an equivalent to the DPS5 offered by EFI Live. The mistake I madeis I got the Insight CTS2 and not the PRO, but Edge offers a software upgrade for $150 if you don't have the pro.
Just as a note, and happy hunting

I know I'm late to the thread but wanna thank you guys for helping me out. This thread has been a big help
I am going to play with some of the tunes posted and update on mileage. I am probably going to alter the 77 HP tune and combine it with the lockup tune. Thank you for the info on the Edge Pro!!!
UPDATE: I reworked some of the number of the 77 HP Hypertech tune and the lockup tune and so far, I'm very impressed with the results. I might play with my shift points a little to kind of dial in the shifts, but overall, I give it 4 out of 5.
- I'm very excited at the fact that I finally found a good LB7 thread because I was starting to lose hope. This has given me a base starting point on my diesel tuning skill, and I want to thank everyone in this thread for contributing.
- What I've done with the tune this far: Changed the high RPM fueling (reduced from 154 to about 120)
- If anyone would like to look at my log I took, that would be amazing.
Thank you again, guys

I am more familiar with gas tuning but I have a friend who wants me to tune his LB7. Thank you guys for the information in here...it is few and far between for these older duramaxes
ive got a stock trans and built trans dsp5 file for efilive. the built trans tune makes around 425rwhp on the biggest setting. both have been ran in trucks for about 10 years or so now. not sure if they can be switched over to hpt file but could download efilive program and open the files and get an idea

I tried to read the truck but it failed so I'm thinking his computer is bad.

I tried to attach the error code but it won?t let me. I can email it to you. Thanks
Yeah I?m not sure. He was using a cheap tuner and he was having problems with it so it might have corrupted the computer. I can email you the hp tuner error message.
I am not able to post it for some reason.
