Just looked up what exactly a UDP was/involved... from my reading it slows the alternator, water pump, power steering, and a/c. Is this a good thing?? I understand the concept, but won't it mess with the performance of those components, some of which I'd say are pretty vita...?
This is a daily driver car, so I don't want to tinker with anything that might degrade my car in the end. Any issues with this change?
