It's always been a given that comparing boost levels on a M90 was irrelevant, therefore comparing boost numbers from an M90 to a TVS is pointless as well. I think he was just pointing out the most noticable change.
I laugh when boost numbers from a turbo is compared to M90 boost. An unefficient 14psi from an m90 is probably making less power than a turbo on 6psi. His TVS should do well, probably a 15% increase, but some of the logic in this particular thread fails at proving him wrong.
He said he's shooting for the dyno on Sunday. A speedo run won't give us anything but another 100 posts about nothing. Dyno and 1/4 mile will shed some better light.
