Regarding gains. Its hard to know gains with out know exactly what it is doing now. I will say my personal prediction is that the supercharger guys will probably be the ones that gain the most from the VVEL tuning. The VVEL is probably tuned very close to max power for the stock NA motor, which will be higher valve overlap. This will effect the supercharged cars more because the boost will blow right through the engine. The turbo cars will not be effected as much because the turbine side of the charger will create its own back pressure on the engine and limit the boost blowing through the motor. Not saying gains will not be possible on the turbo and na cars, but i'm guessing its the SC guys that will be loving that mod.

As far as the twin charging questions .... talk to GTM i know that there Supercharger kit will fit on the engine at the same time as the twin turbos. Obviously the piping and IC set up would have to be custom though. Just have to find someone to step up and have the first compound charged Z.
