Predator says that their product won't void your fact warranty but they recommend that you detune you vehicle before it goes in for service.
I have now had THREE Predators with the same problem. They have writing/communication errors or script errors and will not load the performance tune or restore my factory settings. I have spoke with their techs many times and everytime they have decided it was a bad unit. This third one has the exact same problems as the other two. I'm wondering if there is something wrong with the diagnostic port on my H2??
I have not heard from any other owners with this problem though. Honestly, IMO most of the performance mods provide very little HP/torque/mileage or whatever else they promise. Just put your $ toward a supercharger if you want to see a real improvement. It is also the cheapest hp per dollar add on.
