Not a clue. Some seem to have problems, others will run for years with no issue. Sounds a bit like power supplies we get at work from China. Some are good, some ain't so good...

The ones that I have had go on me have resulted in the car not boosting above 0.5bar. Having seen a previous thread though, it may give rise to massive and uncontrolled boost spikes which cause catastrophic engine damage (bent rods....)

Apparently, some BCS's will emit a "ticking" sound if you listen after the car has been driven hard. Personally, how you hear that with a hot turbo and exhaust that is contracting like mad, I don't know.....!

I heard that can not deliver full boost like when your putting your foot down and giving it some it splutters and holds back also
