Sounds like you are talking a higher level of tune. I was thinking about 450hp, you sound like you are thinking in the 600hp range.

ITB's I suspect is more about throttle response as they eliminate the volume between the throttle body and intake valves. The may add some power in an extreme build targeted at a very competitive race class. The not necessary for a big HP motor that can overwhelm a long hod chassis if not built right.

Motec is excellent if you have a good tuner that knows it.

I guess I would say, start with a lot of money and find an experienced builder to protect your investment if big, big HP is your goal as there are a lot of other little detains like if you should go to mechanical valve train or such.
