Thanks for the nice R&D - kudos for the contribution.
So from what I can tell this is different from other TD06H - 20G's in that it has:
1) Inconel wheel - is it lighter?
2) Custom housing - maybe better? Is turbine housing like 7cm or 8cm 20G?
3) 18psi actuator - seems a bit high, but should help build boost.
4) Looks nice - what kind of coating is that - just paint or ...?
