I have the Banks power PDA stacked with a smarty. The banks by itself adds a pretty good kick in my opinion. Some people will tell you it was money wasted because you can get more bang for your buck, but Banks has some really cool features that I think you will like. What do you use your truck for? One thing you might want to look into is a torque converter and valve body if you are going to run the six guy on the upper settings, because I broke my tc with the six gun alone.
