I have a turbo smart valve. I can switch between 10 and 16psi. I'm just confused why i have (looks to be) a volvo boost line and no OEM guage.
Unless... Does the volvo ECU come with a MAP sensor? My modded 480 turbo had a remapped ecu with a 3 bar map sensor added.
oh the fun of 25psi on a T25 and FWD. Shame the autobox was not friends lol.
