Whelp, figured it out. Intake pipe came off throttle body. Probably didn't put it on tight enough when I did the PCV. How do you make a post say solved?

It's certainly some sort of leak. Went for a drive with MAF unplugged. Past 2500RPM it sounds like a racecar, but has no boost. Gonna have to check the intercooler and anywhere else for obvious leaks.

If you ruptured a hose anywhere between turbo outlet around back to throttle you'd have your symptoms. Intercoolers can split at core to end tank seam also so that needs to be checked. The turbo can pump air out of the leak as it is driven enough by exhaust the moment you start engine to force the ...

My V70 died while I was driving, immediately after flooring it to get up to the speed limit with a blind corner behind me. Lost power, then after about 5 seconds the ...
