Unplugging n75 valve. This is why you can substitute an N18 for an N75. This graphic shows how boost pressure from the turbo Adjusting the N75 valve to the left will "open" it, enabling more air to escape from the wastegate when N75 is opened, which will result in more boost (coz wastegate wont open), BUT Unplugging the N18 allowed me to drive it. Replaced a very frayed vac line . Would a bad N75 valve cause a gradual loss of boost over time? I'm now only getting 6psi at the most, a month ago I was getting 7-8psi and in the winter I was getting 19psi, needless to say my boost had From what I understand, by unplugging the N75, I should be limited to 5-7 pounds of boost.
