5858 no boost?
I had a 5858 turbo kit with built 2.0 tuned by english racing running at 26psi. I was on the freeway wot on 4th gear about 6k rpm and shifting to 5th gear, all of the sudden there was NO boost on 5th. I did not notice any weird sound whatsoever, boost gauge still shows negative pressure on idle. Engine was idling just fine. Will it be the wastegate got stuck open or the turbo failure? Any other thoughts will be helpful.

Check for charge piping blown off

If the turbo failed, there would noises and smoke. If the wastegates were stuck open, you would hear exhaust constantly coming out of the dump tubes. Make sure something didn't go through the intercooler

Yeah, sounds like your classic massive boost leak.
