A old vehicle had regulator 3 bar for standard engine and 3.3 bar for supercharged engine. It was an odd-size part, and Bosch no longer makeit. Maybe a few sitting in a warehouse in Germany. There is one third-party copy part, but only with 3.3 bar pressure. Presumably the higher pressure would go with different injectors and ECU map. So if one put in standard engine, what would happen? Perhaps it runs rich for a while, and will be trimmed back?
