Post by: Charliegti on 12 March 2014, 20:55

Hi folks I am having a bit of a problem With my golf it is a 1.8turbo it has been running at 15 psi of boost and now just after 10 psi the car looses power and throws me forward and looses all boost it is fine when cursing but when power is needed problem starts I have changed the the maf and n75. throttle body sensor. Does anyone on here have any idea to the cause or how to fix it. Any help appreciated.

Mine did the same when I had a big boost leak hit about 8 psi but you could tell it made a massive noise
