This 5.9 Cummins With A Smarty Tuner Can Roll Coal Like It’s No Ones Business!

There’s so many people out there that assume that they should be able to roll coal the minute they get their truck off the lot. Well unfortunately that isn’t true. If you want to roll coal, your truck must be tuned for it. Many people choose an EFI Live tuner, but this guy decides to go with a Smarty Tuner!

This 5.9 Cummins is tuned to perfection. Not only can it roll coal like it’s no one’s business, but that thing sounds mean as well! Personally we prefer the efi live tuner, but this Cummins is making us question our choice of tuners. We may need to go switch it up so our truck can sound as good as this!
