Hey guys
I dont know what to do right now. I have a stock 07 5.9L with a mbrp muffler on it and I get about 20mpg hand calc. I would love to get a few mpg's out of her and I'm wondering if a smarty jr. would help me or just make it faster. I would love a little more power but its not high on my list. Any help would be great.

Very happy with mine so far. Really like the low end throttle response and cool egts.

Smarty= It would be a real good choice!

I would try a DR Performance Predator module. We run them on our 2003 & 2006 trucks with great results. You will see a very nice bump in your MPG's & pick up 110hp / 220tq. I've tried quite a few differant products & these have far out performed the others for my needs.

those are both good programmers but seems to me for people not trying to make "super power" juice, bullydog w/monitor, or a quadzilla works great. Cause you can have the power and mileage all within arms reach! But thats just my .02 cents! Plus you get guages!

With an 07, I would be concerned about warranty preservation. Heck, I'm concerned about it on my 04.5 (Cummins and Dodge Power Train warranties). I know that the Smarty Jr. advertises that it leaves no footprint when removed. But, do you really want to put your warranty on the line for an MPG or two if, down the line, the Dodge boys figure out a way to sense that a S-Jr had been installed when you bring it in with a toasted tranny or injector? This is especially true since you don't care that much about the added power. For me, it wouldn't be worth the risk.
