Looking to get the VCM kit, just wondering if I REALLY need the pro version? I will use it to change out tunes and monitor what I have. End state for the car is to put in the wr3/ddm efr kit and be done with it (I want ~450hp). I wouldn't tune the car myself. Just trying to justify paying extra for something I wouldn't use? Or am I missing something it does I am not seeing?
