Hey Guys, Just done all my stuff to my car which included 60lb Siemen Injectors, Walbro GSS342 Fuel Pump, HDi Intercooler and Turbo with bigger flapper and such. I put the tune I have for the 60lb injectors and it runs nice, but im only getting 5psi but should be 8psi... Now could this be the Intercooler dropping the boost? Or could it be the wastegate keeping open? Seeing as its a new turbo and such we were checking the actuator and it was alright but it was on border line and further and it be open so yeh just seeing if anything can think of a reason... Before you say anything its going in for a custom tune but because of the V8's everyones booked out atm.
