Hello everyone,
I'm new to HP tuners because I know next to nothing about them. I would hopefully like to learn as much as I need to know to correct a problem with a 2016 Dodge Charger Scat Pack that I bought from another state that had a HP tune done when a Whipple supercharger was added and now it won't pass state inspection in my state (Vermont) because the system stays in a "closed loop" and the oxygen sensors have been turned off according to my mechanic. The original tuner told me that he did preform an HP tune on an aftermarket PCM he installed in the car and that the tune is "unlocked" so it should not be too much trouble to correct things so the car will pass state inspection. I have no idea of what equipment I would need to do this or if I should even attempt it for fear of messing up the systems in the car. Any advice or help would be sincerely appreciated. Thanks !
