Does anybody on here have any suggestions on what to put on a 07 with the 5.9? I have been told the edge is better but not sure.. thanks.

I would buy a SMARTY if it were me, but u need to get some gauges so that u will know what is going on with your truck especially your tranny. Is your tranny stock? I had a SMARTY and sold it and now I wish I had it back.

It depends on how far you wanna go with power. If u wanna upgrade a little and leave the power kinda easy go with edge juice. If you wanna go insane power like heavy fueling and big singe turbo or compounds go with smarty sr. The edge is very safe so u will not melt the motor with alot of heat, it has built in safety.

Somebody on here had a 8 month old Smarty Jr. for sale for $300. That's bargain power.
