If you want to get down to it.. its damn close to impossible to use 100% of the exhaust energy. they may use a little more as with the variable vane, your gonna use more of it durning the low end as the turbo's exhaust housing is restricted, thus causing an increase in velocity, spooling the turbo theoretically faster.
just for fun and discussion, anyone feel free to debate if this seems out of line.
what drives the turbo is heat, and the pressure differential across the exhaust housing of the turbo, which is generated because the air is hot as crap in the pipe and wants to cool down, thus getting out of the pipe, so the more heat you have in the pipe, and the faster it can excape via turbo/downpipe, the faster its gonna move and spin the turbo. so going with the idea that heat drives the turbo, to claim 100% of the energy used, the gas excaping out the downpipe would have to be the same as the ambient air temperature. this is relatively speaking impossible. I dont meant to be a nay sayer on things, but I just dislike people making wild claims to support their product, while in fact, the physics/chemistry are a little different.
I guess that could be said.. BUT... those two 100%'s are VERY different, and even so, with a vatn turbo, with the vanes opened up super far, its basically like a strange sort of internal wastegate. Either which way, I am still waiting for the aero guys to come on and follow up. they seemed to be eager to tell us how badass ther kits are, but not so good at telling us how it all is dealing with known issues.
and his comments about leaving the stock map intact leads me to beleive its just a piggyback injector setup.. easy to do, and a fool could dial something like that in pretty easy, sorta defets a lot of the etec gain, and just adds more clutter.

This is the only way you will be able to fuel a Turbo'd Etec, is through a piggyback injector setup. The Etec Direct Injection system is going to be mechanically limiting. Skidoo is already varying the fuel pressure themselves so trying to fuel a turbo through the direct injection is going to be nearing impossible, unless you are the designer of the Etec fuel system.
The standalone systems maybe easy to tune but cost a lot of money. Plus all your standalone ecus are going to require certain inputs to build a fuel curve (temp sensor, tps, map, rpm, etc.) So are you going to add all these sensors on the machine cause the standalone ecus out there aren't going to work with skidoo sensors.
