cheapest way to get hemi 3g going?

This thread pops up every time I search on google for info, so I'm bumping it with this link.
https://www.diyhemi.com/
I'm sure it's been posted FABO a thousand times.....
The videos are hard to use on the site. If you tap the youtube icon it will make the videos user friendly.
EDIT: This still is gonna be expensive. But here is my route I'm thinking of:
Using hptuners vcm suite. That way instead of buying a part, I'm buying a powerfull tool.

Also, please dont butcher me if there is some thread with the info on here. Instead copy and post a link.

Please.
