I think you are missing the point Pete as some of this skepticism is justified.
While transitional response is to be commended by the seat of the pants experience and dyno, the mph numbers just don't stack up.
20 psi on 93 makes 370 wkws and pulls 120mph
30 psi on E85 makes 500 wkws and pulls 132mph
This is why people are skeptical and it needs to be highlighted if people are considering various turbos for their build.
Not having go, as long as people are happy with the performance who cares, but the mph really hasn't demonstrated these turbos are flowing any better up top than old tech which is similar to the GT to GTX data, yet dyno numbers are generous to say the least.
Back to back is great, but let's also see some mph supporting these peak power figures.
I am actually looking forward to Piggaz posting up his results as his setup seems spot on for big mph if the turbo can deliver.
Ps: if a moderator is not happy with this post just pm me and I will stop posting.
