Hard to think of anyone who better merits that fine machine than Jeff.
The best I can offer is a little diagnostic suggestion: ride around with dual vacuum gauges. They can provide you with a whole world of "insider" information and far more than a TwinMax (which only reads relative pressure and in unknown and arbitrary units, not absolute pressure in conventional units). A special issue they might illuminate is the butterfly-on-a-wire and what the stepper motors are doing while you are busy driving. Even if all indications are that the breathing is more or less normal and the same on both sides, that reduces or makes less likely a lot of possibilities. I assume the Moditec or whatever reads from some vacuum ports somewhere on the TBs.
Might cost $50 for a pair (be sure to get snubbers and/or raid your office for hemostats!). And some duct tape. Or buy three and return the one most poorly matching the others.
