just wondered if anyone has come across this before.
Suddenly today my Defi boost gauge started dipping an not responding properly during low revs, below is link for video.https://www.youtube.com/watch?v=enE4qmqxD5Y
turbo spooled up ok, and oem gauge showed its spooling.
The defi one should creep up to '0' when I rev it like that, but its dropping down. It did shoot up to above 0.5 when I took it out but then drops straight back down to near bottom.cheers for any info
