Hmmm in saying that, do you think that there could be some sort of switch on/off built into the computer system? In order to shut off the larger turbo through 0-3500rpm, then turn it on 3500-7/8000rpm and vice cersa for the smaller? Sounds stupid and i figure it would be hard to simply turn on and off a turbo but interesting to know.
Also Lithium, assuming the motor was built with (im guessing) some type of valve variation, eg say a VVTi system with its own maps for valve timing for each turbo. would this work? Or am I simply making stuff up in my head? lol
