I have Bama's tunes (for my Predator). They really wake up the car, and are a HUGE improvement over the stock tune and also the Predator canned tune. You really can't go wrong with Bama, Breenspeed, or Tillman. They are all great tuners and have a great reputation here on AFM.

Is your car a stick or auto? I have heard Bama does great for an auto.
It is pretty simple to load the tune onto your tuner. Just need the software and a cable to run from your computer. If you have a laptop you can power it from your car, but if not you will need to buy a power pack (at least for the Predator).
