Get whoever you want to tune it. Everybody is on the GDE fan boy trip. I have a GDE tune as well but I'm my opinion any tuning company can do the same job or close to it. A tune is only as good as your supporting mods. If you tune and don't free up your exhaust and intake then you won't see much out of it and you are stressing out your turbo and motor a lot more. Straight pipe exhaust... upgrade intercooler and piping. And you will see a huge difference more than just a tune. Read up and do neccasry deletes.. and get the most put of.your jeep and money.
