So i have a 2012 1500 sport and iv been trying to figure out which tuner to get and what specific tune is the best. all i seem to be able to find is old info, anybody have any new details? any guidance from people who have same truck? would welcome any help!

 

The most popular with this model is the Diablo I2 or Trinity. If you need to disable tpms then I'd suggest the bully dog 40417. With either of these you can get additional tuning that's better than the preloaded tunes. The 40417 doesn't have as nice a data logger as the Diablo units though. But power output is basically the same.
