Got a 3076 BB sitting around I want to install. The turbo is a direct fit besides the intake. Anyways I would like to install this and am wondering if I need to tune. I know the 07 spec b has a OEM boost controller. So will the ecu know the difference with the boost levels within the rpm range. I am not going to just throw this on and cross my fingers. I have headers, up pipe, down pipe on the way. Plan on gathering parts for the build and dong my research before major install upgrades.
