Which tune should i get?

[badss]

I have a 2003 5.3 regular cab and im just going to add an intake to my exhaust cas im going to drop a new engine on down the road. I want a computer tune, there is about three out there that i have been told about but which is best for my truck?

Take your pick.. Nelson-Black Bear-Wheatley, are all great tuners, I doubt you will actually be able to tell a diff in any of them..
