Title: Gti 2007 not boosting hard
Post by: raygti5 on September 18, 2013, 11:22:20 am
hi guys

my car is not boosting hard but its boosting. the turbo is spooling and its dumping.. is there a simple test I can do to check whats going on?
I secured the induvtion kit properly and it feels slightly better as the previous owner did not even clamp it to the turbo!!

many thanx

Check the DV!
Smoke test it for leaks

Check what revision DV you have on the car at the moment. I had similar problems and changed the DV to a revision G and the car felt a lot better. I recommend you change the DV anyway its £39 from VW and you can probably change it yourself.(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fimg.tapatalk.com%2Fd%2F13%2F09%2F18%2Fbu3y2a7u.jpg&hash=d5fd795fbe0a28c9ae5a1b209a6102a2627aec02)
