See what sort of feel you get from the engine with it open or closed throughout the whole rev range. This might help diagnose any problems.
Try it with the Camry too to compare any changes. I know the Camry is Auto and heavy but you should notice difference and be able to compare similar feelings in power and torque.
Will definitely have to give it a try. I picked up a spare vacuum canister and ACIS flap/diaphragm for next to nothing if everything else fails. Have a long drive to Wellington that I can test the different plumbing on
