What Cummins 24V chips/ tuners/ boxes/ you like or not?

I have a '05 Ram 4x4. Researched TDR and most of the other web sites, settled on a Smarty 06 programmer. good power and mileage. The big problem with any programmer is getting carried away with the power settings. I smoked the factory clutch in the first week, and scared the hell out of a lot of other drivers before setting it to level 3 where it has stayed for over 100K. the only other mods other than the suspension is a K&N air filter and a South Bend dual disk clutch. One the best thing to do is to add wally world two stroke oil in every tank. It helps lubricate the lift put and injectors, and just idles smoother. I would also adjust the valves. Good Luck.
