No i HAVENT gotten a protune for this yet. Its only been on the road for like a week and it was basically spent breaking it in.
I still have to get it inspected at Canadian tire before i can put my front mount intercooler on, I only have a 02 WRX TMIC on it now. I dont want to protune until i have the FMIC on.
So i did what u said and i unhooked the line... it only SLIGHLY increased the amount of boost (9psi). So it must be a pre-turbo exhaust leak then?
