5.Use the new open source program called Universal Patcher.

All the options have pros and cons, it also depends how good you are at new technology.
kur4o, appreciate your thoughts.

1. I am assuming you talking EFI Live or HP Tuners?
2. I dont see a downside to downgrading it to a 2004. I engine will be running on a stand alone factory harness. Is there?
3. I not that computer savy..... LOL
4. I may have a local guy that would be able to if #2 doesnt work out.
5. Have you personally used Universal Patcher? I saw it and played with it on various matching bin and xdfs on the site. It says it works when I toy with. But then again I can be blind folded and served a steak but is it really a steak. Maybe a bad analogy. but.....

New 6. Go to the junk yard and find me a 03 04 05 ish pcm and play with it. As I know I need dbw. I dont care what year the os or pcm is.
