Hi I have a 2007 Dodge Ram 2500 Cummins 6.7L and I wanted to get more horse out of it because I just got beat in a race against a Chevy Silverado and I'm pretty pissed

 

There are many different tuners out there. But be known that adding power to these trucks also increases wear and chances to break parts. First I would look at getting it deleted, then move to getting it programmed. The more power you throw at it will likely make the transmission die, I assume its still stock.
