Smarty JR Programmer Reviews


Looking for fuel economy

Reviewed By Ed R (Boise, ID) —11/28/2015 4:14 AM

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.

This is by far the best programmer, my 2009 dodge 6.7 is a whole new beast it exceletates like a sports car and torquey like a diesel should be now. I would recommend this programmer to anyone.

smarty jr.

Reviewed By Terry P (PADUCAH, KY) Reviewed for a 2008 Dodge Ram —11/13/2015 5:05 AM

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
