I have a Audi A4 1.8t and I just put a to4e turbo with external wastegate ,and bovand I am getting almost no boost
it goes up to 4, 5 psi in 2nd but there is no boost. Also my bov is not blowing off im thinking it has something to do with that but i want to be sure .Also I dont have any vacuum line going to my n75 but the electrical connector is connected could that be a problem. And one more thing ,you know how theres a fitting on the ko3 charge side of the turbo my new turbo doesnt have one . Do I need to install one so I can connect my mbc or do I route it somewhere else. thanks

 

yeah, you might want to take that BOV off.

 

I took off the bov and installed my diverter valve and still no boost. actually if I give it full throttle I get 5psi in 2nd
