This programmer is ok...I researched long and hard on what programmer to buy for my 06 dodge and everyone raved about the smarty. I have one question, WHY? I mean the power change was noticeable but I'm just not impressed with how the truck performs. My biggest dislike is that you have to release the throttle to get the truck to shift from 2-3 and 3-4. My other complaint is that it still feels like STOCK until it hits around 2500-2800 RPM. I want something that has power from the get go! Also for the money I would rather have something that has a color screen that is more user friendly and has more options. Last complaint is the smarty looks like a 10 year old built it and is not user friendly. I never could figure out how to download updated versions for my Smarty JR.

this tuner is amazing. i found that the 100hp is great power when racing, but i normally just keep it on the 70 and get 26mpg hwy and 19 in the city. i would buy this again and aigan!!!

2005 Dodge 2500 Cummins. Works way better than I thought it would. Used the 2nd level. Plenty of power. I would recommend this to anyone.

Installed on my stock 06 3500 mega cab with auto trans. For a heavy truck this thing now hauls a... Huge difference in power even at mild settings. 3 mpg gain averaging 15.5 short trips, city driving and damn cold weather. Looks like about 18 straight down the hwy no load. Around 13 pulling a loaded 24' 5th wheel horse trailer. Very Happy!

Smarty products are the best on the market. I wish I had put this on the day I bought my truck. Excellent driveability and power along with infinite settings. 3 mpg fuel economy improvement. I extensively researched all programmers before deciding on this one. The way to go is SMARTY.

Just installed Jr.. Went straight to level 3 and its amazing. My '06 with just a modified intake and a cat back exhaust will now light up the tires just punching the accelerator with a non boosted launch and it really does pull you back in the seat. Throttle response seems to be better as well. There's a little more smoke than I like but it's only moderate when I first hit the accelerator when getting on it hard. I haven't got exact numbers yet but boost is higher and EGT's are lower. I'll be switching to level two soon to tow 32' camper and will try to post review about that. This is the only programer thats been on this truck and I can't imagine any other working any better. I HIGHLY recommend this product. Thanks to XDP and to all at Madds electronics for making the Smarty.

I just got this in the mail today. Pulled it right out of the box and plugged it into my 04 5.9L. Tried out the sw:2 setting first and was really impressed. It gave the trans better shift points also noticed a huge increase in power. put it on sw:3 and it blew my mind. I've heard that it's hard to get the 03-04 5.9s to smoke or get power but defiantly a huge change. I am extremely satisfied with this product. And the guys at XDP were awesome.

plugged it in on my 06 5.9l with an exhaust and cold air, and i didnt realy get the mpg gain i was looking for 2mpg better tops on eco and tow, but if you dont dog your vehichle hard you can run this thing on sw:3 99 and notice a huge difference in power can drift my truck on dry pavement all day (not reccomended) deffinitly pulls harder, i keep it on stage 2 50% of the time to be safe but it did what its suppose to do as far as power.
Bad ass
