2004 tuning and questions

Bare with me I'm new to the 03-05 Cummins tuning. I've tuned Duramax's with EFI live and 07-09 trucks with EFI live I've got some questions.

#1 I need a 2004 stock tune file from some one and if you have one THANK YOU in advance.

#2 What is the best way to go about writing a tow tune and a fuel economy tune?

#3 What should be safe zones on a 2004 like a safe timing to stay under, rail pressure, and microsecond?

Help is much appreciated thank you!

For stock tune you need to read the truck you wanna tune

Tow/economy tune need some pressure and timing to have good atomization and kind of cylinder pressure(more torque)

Safe level...max 2950us max 24000psi max timing 31?
