Install was not real easy, I had to update the software multiple times. Allow plenty of time to do the initial install, took me about 2 hours. Can't believe the performance improvement over stock. Haven't checked yet to see if any improvement on gas mileage (didn't buy it thought for gas mileage). Well worth it.
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
