Big power gains don't have to come at the expense of busted knuckles, greasy fingernails and wasted hours under the hood. Boost your big rig's output the easy way with a Smarty JR Programmer. In 5 minutes or less, the Smarty JR optimizes your pickup's onboard computer to unleash up to 100 extra ponies and a ton of torque from your diesel powerplant—all without turning a single bolt, screw or nut.

With the Smarty JR Tuner on the job, you'll tow harder, climb hills faster and pass slowpokes in a flash. Just plug it into your OBD-II port, pick from the 3 tunes and you're set. The advanced CaTCHER software of the Smarty Junior gives your throttle hair-trigger response, speeds up turbo spooling times and even improves your fuel economy—it's the performance trifecta. Plus, you can switch between tunes on-the-fly, thanks to Power on Demand.

More than just a power programmer, your Smarty Junior Tuner lets you customize key settings and gain insight into your engine's health. With a few clicks, you can update your tire height, adjust the high idle and check diagnostic trouble codes in plain English. It plugs into your PC for easy updates and is backed by a 1-Year Limited Warranty.

Smarty Jr.

'04 Ram 2500 Cummins with 35" Nittos. Not being very tech savvy I chose to install Program #2 (towing) to compensate for the oversized tires and for more torque while towing our 23' toy hualer. Installation was easy, including recalibration of the speedometer. Better throttle response and more power were immediately obvious and my fuel economy increased by 1.5-2 mpg. The truck also tows our trailer with much less effort. I am very satisfied with the Smarty Jr.

Impressive improvements

I have an 07' Dodge 2500 with the 5.9 Cummins. Intake, exhaust, and gauges. I uploaded the tow tune and corrected my tire size to re calibrate my speedometer. The power improvements were very impressive and the power delivery seemed much more refined. Very happy with the purchase.

Very Happy

I could tell a huge difference in towing, my truck didn't seem to have to down shift as often and it was very smooth. I would have liked better mileage but I'm happy with the towing performance

I haven't had a chance to play with it a lot, but first impressions are good. One thing I don't like is the instruction manual that came with it. Should be a lot more in-depth. This is obvious because Mads Electronics is answering a lot of questions on their website. Mads is doing a good job with this though.
