I was skeptical about the real world results of a programmer but this is what I've experienced... - 2-3 mpg improvement (if you can drive like normal and not stand on the gas when driving) - towing mode works great (I used it to pull up trees in my yard) - great user interface and easy to use - is expandable with the EAS system - was super easy to install - I experienced a noticable exhaust note change with factory exhaust. Is on a 2015 Chevy Silverado 1500 crew cab
It honestly could be too much for this truck. I have a cold air intake and a BBK throttle body install so I thought it would be a nice addition. Put it on setting 3 and apart from running loud and fast it gets 4 extra mpg. I put it back on stock and the mpg improvement is still visible. Great product, ugly logo.
