Simple LML tuning

Hi guys,

Super newbie. I have read Greg banish's book, and the GM master EFI tuning book, but they don't touch anything on diesels. I am keeping my truck stock, but would like a little more get up and go/ improved pedal response and more mileage if possible. What are simple things I can do to my 2015 LML? Also are there any diesel tuning books out there? I understand HP is limited on the diesel front, but I'd like to do whatever I can since I already own HP.

Thank you,

-Jess

Add fuel in the torque to fuel mostly in high rpm works best for me and advance your injection timing a few degrees set the torque limiters off to let it fuel

Thank you
