You might get limited power increase but I do think you would see an improvement in driveablilty if you drive your car year-round and live in a climate with that varies the seasons. I'm a hard-core CIS guy (I like CIS) but keep thinking about doing an upgrade just to improve cold weather performance in Oregon. I think that EFI with a common intake plenum may be the way to go in my case, but ITB's do just look mechanically-easier to implement.
