and the 987 maf comes w the housing, unlike the 986 part.

to Q, you have a 2003 so 7.8 dme. you want a flash for a car w the larger maf holder and the improved variocam (but not variocam +). you are limited to the se flash or *perhaps* a 987 boxster flash. 987 boxster would be excellent as it would have the programming to drive your new flapper, however i am uncertain if it would work well on a 986 car - i *think* the 987s have other programming built in to the dme such as traction control; it may not function properly as all systems are not connected (i've asked this question before on several forums and never got an answer).

otherwise, i had done some research previously that had indicated that the plenum flapper was controlled differently than the resonance valve (worst case, check the wiring diagrams for the 987 - seperate wires for each would indicate different control - or get someone with a 987 to have a look). you could delete it altogether, or use a solenoid triggered by the same signal as the resonance flapper, or use an rpm signal to trigger (if you new how it was supposed to function, you could build an rpm-triggered window siwtch to actuate it).
