there are whole lot of options for ya.

edge
banks
diablosport predator
ppe
hypertech
superchips
van aaken
quadzilla
bully dog
just to name a few...

my dad has had the edge juice with attitude on two duramaxes (04, 07) and it has been a pretty good tuner. couple problems here and there, but edge has always backed the product 100%. they also make the evolution which is a programmer. both of those units along with the banks, and bully dog have gauges with them if you order it. the banks is also a very good kit that will give you safe power and mileage much like the edge, but it is a little pricier.

edge with attitude... set it on level 3 ALL the time, you'll NEVER be happier.. Dad's 1 ton dualie went from 15 to 18.5 mpg empty and from 9.4 to 13.x pulling his 24 ft fifth wheel...(and that included pulling it over wolf creek pass, in southern colo.)
