I'm just saying, other 2.0L vehicles and 86's running this turbo or smaller turbos hit higher boost. The turbo will do 25 psi I bet. Maybe more. It might be out of its efficiency range, so heat would be high, and there would be no gains in power, but that isn't my point. He said his turbo was so small the wastegate was always closed, which essentially is like running with the vacuum line removed. People overboost in that situation. I'm sure he has fuel/spark/throttle cut to avoid overboost anyways, so the point is moot. This is why I asked earlier if he had boost drop across his massive FMIC, which drastically reduced temperatures, so pressure dropped or something, but I still feel like he shouldn't have enough drop to justify having such a low boost ceiling.
This guy has a EJ205 WRX and the same turbo at 20 psi.

Not really sure why it says wastegate then he is saying his wastegate is always closed. I'm just confused.
