Guys I'm completely new here, first post. I'm going to buy EFI and want to create my own tunes that way in the future I don't have to continue to pay someone for new tunes when I add new mods. The question is, where the heck to start. I've downloaded the software, but don't have the actual V2 yet. I want to be ahead of the curve when I get the hardware.

Back on track, where is a good place to start with EFI tuning?

Thanks for the welcome. I'm all about doing things myself, I guess it's that weird satisfaction thing. Is there somewhere/someone in particular I should look at to get a first tune?

Go on Duramax Diesels and look at tunes there.

Rarely will you ever get good tuning advice here. Nothing about it is easy if you aren't familiar with it.

start by logging.
Most people kill off the post injections.
raising fuel pressure where you cruise helps mpg's.
I like to start by pushing the timing to btdc, factory is atdc.
You will notice a degree or two rarely makes a difference in economy.
