I am just wondering if i raise the fuel pressure do i have to remap the car?I think not because the injectors are programmed to inject a spesific amount of fuel.Also if someone already has the 3.8bar regulator that Barbz is selling can he tell me the Bosch number written on it?
You will need to remap the car. Increasing the fuel pressure will increase the fuelling across the full range, so some sections will be rich and some ok.
