Another thing that guys, especially with manual transmission trucks notice, is that the Smarty makes gear changes much easier because the power kind of "hangs" so you don't have to come up on boost as much between gear changes. Couple this great power with NINE power levels, and its hard to pass up a Smarty programmer. Oh yeah, and you probably want increased fuel economy, too, right? Guess what, Smarty's work exceptionally at increasing the fuel economy on your 6.7L Cummins without making ANY other modifications!

And because we get this question day in and day out, how will a Smarty affect fuel economy? Well, we have good news for you! Smarty did extensive research and testing to increase the fuel economy as much as possible with ONLY the addition of a Smarty. In order to do this, they had to determine the best way to increase the overall efficiency of the engine, in turn also reducing tailpipe emissions, which also reduces the number of regeneration cycles the truck performs. And more good news, they accomplished it. To prove the results, Smarty had independent testing performed which delivered a 4.15 MPG average increase and a 24.26% decrease in carbon dioxide tailpipe emissions. Don't believe it, CLICK HERE!

  • Do not use power levels 8 or 9 for prolonged high-speed runs! Speeds exceeding approx 105 mph can result in high exhaust gas temperatures and damage the Diesel Particulate Filter (DPF)!
  • All even-numbered software (2-4-6-8) without timing are to be used for stacking with other aftermarket power adding devices that also add their own timing. NO additional timing has to be used with the odd-numbered software (1-3-5-7-9). Severe engine damage will result!

It is now possible for the customer to dial in the VGT responsiveness. What does this mean? You can change from the default settings how responsive your turbo is depending on your driving style!

The VGT levels are as follows:
1) stock ( makes for a somewhat sluggish throttle )
2) The Default one, good compromise between responsiveness and MPG
3) For Mileage! Less responsive than 2 but better for mileage ( Should be used for towing heavy )
4) As responsive as possible without creating too much backpressure. Mileage will suffer a little with this one!

Smarty software updates are always free. As an added bonus, you can always send yours in and we can do it for you. Local guys can always bring theirs in for the free update. We will even help you program your truck!
