Was this pull done in 4th?

We already have seen how a gen2 compressor wheel on the PTE is worth 30-40hp over the same exact sized gen1 wheel. Then add in im assuming the new technology and r&d of the 70mm, and its not making a good bit more power at a respectable 40psi?

Again, reread what I posted, in particular the last few sentences.

Also leaves room for more if focus changes and they decide 50+psi is a good idea in future

Thank you for sharing as always
