Description

Smarty S67 Tuner by MADS Electronics 07.5-12 Dodge 6.7L CumminsSmarty. this is a name that has been synonymous with Dodge Cummins for years. It's hard to describe to someone what is different about a Smarty tuner versus "others" until they drive it. Even with having similar power levels to other brands of tuners, Smarty has the leg up on drivability. Think of it this way, while there are many other tuners on the market that make the same power (if not more) than a Smarty, its all in how each GETS to that power.

Smarty.... this is a name that has been synonymous with Dodge Cummins for years. It's hard to describe to someone what is different about a Smarty tuner versus "others" until they drive it. Even with having similar power levels to other brands of tuners, Smarty has the leg up on drivability. Think of it this way, while there are many other tuners on the market that make the same power (if not more) than a Smarty, its all in how each GETS to that power. Where most other types of programming have more of a progressive curve that slowly gains that additional horsepower, and finally achieves it at the top end, Smarty gives a much more aggressive curve that brings the majority of that power in from the bottom end, and then carries it all the way through the power band up to the top.

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 effect 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 amount 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.

IMPORTANT NOTES REGARDING POWER LEVELS:

  • 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 after market 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!

This product will not allow for the removal or disablement of factory emissions equipment, such as EGR (Exhaust Gas Recirculation) or DPF (Diesel Particulate Filter).

VARIABLE GEOMETRY TURBO (VGT) ADJUSTMENTS: 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 back pressure. 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!

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
