Hi guys.

My boost gauge has started reading low. My HKS evc reads 0.7bar and my gauge used to match this, now the ebc reads the same but the gauge is only showing 0.25bar. It's still pulling strong though, definitely making some boost.

The way it, either the boost gauge has died, it still reads vacuum perfectly accurately or i have a boost leak somewhere.

What are your thoughts?

I have seen these home made boost leak testers that require a plastic end cap, a valve fitted to them and a pump with a gauge on it. Has anyone here tried making and using one of them?
