MADS Smarty Programmer S-67

smarty 67 is an unbelievable tuner. i have tnt on mine and it's insane on even the lower settings. be prepared to upgrade your manual trans. with an aftermarket clutch as this box will do in a stock clutch in a short amount of time(fyi stock mercedes g56 clutches were weak and junk from the factory shame on Ram!!) I did tons of research on tuners until deciding smarty is head and shoulders the superior product. you will not be disappointed! Oh do your self a favor and order the k&n complete air intake system at the same time. With diesel at 4.xx a gal.mine was paid for in fuel savings in 3.5 months!!!

I farm and use this tuner on my 08. i pull with it all the time. great fuel econ! fast as shit too! overall there are so many things a person can do with this tuner especially with the revo and tnt tune downloaded to it. thats what im running on. its AMAZING!

this is an amazing programmer never had any problems running on sw#9

Unbelievable power and smooth drivability Great towing on #3 setting with manual tranny. Kicks butt on #7 setting.

incredible downloader!!! highly recommend aftermarket injectors fuel system and clutch or built tranny to see its full potential.

this is an unbelievable item its way better than the juice w/ attitude
