EDGE or SMARTY JR

[azwiz]

I am in need of experienced opinions as far as tuners and/or programmers. I own a 2006 3500 5. 9 auto trans 3. 74 rear dually. I'm looking at the "Edge Evolution CTS Diesel" or "Smarty Jr" with "Edge Insight CTS" or any other suggestions. Truck is stock except for intake and 5" exhaust. Also reliable 2 or 3 micron fuel filter setup.
I tow a 12,000 # toy hauler on occasion

Thanks in advance
Steve
