Had a dual stage boost controller fitted today.
I wanted high boost to be 14psi and low to be the stock 7psi. However for some reason my mechanic couldnt get low boost below 11-12psi.
Does anyone know why this could be? He suggested that possibly the car wasnt running 7psi when i brought it in, however to my knowledge it hadnt been boosted before...
Mods include large FMIC, 3" turbo-back exhaust.. (if that makes any difference)
Any suggestions on why the boost would not come down would be most appreciated...
