OK, so this is a question I have been really wondering about. I have a 2003 RAM 3500 with the 5.9 Cummins. I tow a 5er of about 13,000 pounds empty. I have a 15k Hitch. The truck has about 150K miles on it. It is in good shape overall.

Anyway, when I first bought it, I also bought a Smarty Junior tuner. This is a software upgrader for the engine. I programmed it for the highest output. It SEEMS to improve the power, but there is no number I can find on how much it might have improved the performance.

Does anyone know anything about the Smarty Jr tuner and what it can do to a 5.9 (in terms of HP and Torque)? I would like to know how much I have improved the power by using this tuner.

Thanks.
