My friend is looking to try the Tros Potent booster as well. We'll work on his 2.0T next after we finished installing the suspension and all terrain tire on the Wrangler this week.Yeah I always recommend consulting your tuner if you are unsure the route you want to go. If you don't have one, look around and decide if you have a local tuner or need to do remote tuning.
You gotta determine your goals for the car. "More power" is too vague to really give you some ideas. How much more torque/power are you looking for and when do you want it? Stuff like that will help you out. If you just want to see a big number you'd need to put resources into building the engine and a bigger turbo, but it won't be that great from a driving perspective. Some joke and call em' Dynoqueens cause they are really good at hitting big numbers but not great to race or daily.
The Tros Potent booster is pretty popular. A lot of people like throttle controllers to make the car feel more responsive and "faster" even though it doesn't increase power at all. It basically tricks your computer into thinking you are heavier on the throttle pedal. Its plug and play sitting between your throttle pedal and the ECU. Pretty much acts to "boost" the signal so that 10% throttle might be seen as 50% throttle, etc.
