I've been leaning towards Utune for a while now and only because I don't plan to go much further beyond what it offers. BTR seems like it's the best to get if you want a lot of power though. Future plans for myself is a project car and keep this as a daily sleeper.I'm rather undecided between the U-tune and the BTR tune. On one hand the utune seems to play things safer but would really enjoy the ~300hp to the wheels from BTR. Tough decision
