Looking for fuel economy
I am not what would be considered a motor head by any stretch of imagination. I was looking for a programmer which was uncomplicated. Many descriptions and reviews led me to the Smarty Jr. I have programmed my 04.5, 5.9 at level 1. Had little use, since truck is used primarily as RV tow. Most likely,since I am not that mechanical, I have difficulty understanding the POD, along with timing adjustments. So as time passes I hope the factory defaults will suit my needs.
I have had a smarty jr. in my 08 ram 2500 for a mon th now. I read about it on forums for about 6 mos. The tuner does exactly as advertised. it is straight forward to program. I have experimented with it and have it set on sw. 3,timing 3, tq. 3. I have no problems. The power is incredible!Its like I have an 8000 lb. sportscar.There seems to be a lot of confusion on forums.You just have to use common sense. Pick a setting, leave it alone, and don't try to tear your truck upI
