Well I've looked all over for loose hoses but cnt seem to find anything....I was hoping it wouldnt be a problem with the turbo as its relatively new (probs done less than 4k) but from a few things I've read on here I'm starting to think it could be the waste gate penny not sealing properly......


Took the car out for a good run the other day on some long streight roads...Up until 4k the boost gauge is reading a vaccum, at 4k the gauge reads 0. From then on the needle on the gauge seems to vibrate if you know what I mean, then at 5k the guage reads a max of about 27psi

Hence the reason I was thiniking it could be the penny....What does everyone think???
