the first thing I would do is order a Bentley manual from Jim at sobstory 800-583-0370.

The overboost fuel pump cut off switch is under the dash on the driver's side and is adjustable, or you can just pull the wires and connect them together as I said before.

The APC solenoid is not adjustable, but it's good to clean it out with carb spray every year or so.

The wastegate is a metal flap located in part of the turbo housing. It is actuated by a diaphram connected to an adjustable rod(easily visible and accessed from under the car). The diaphram is controlled by one of the hoses from the APC solenoid. You can shorten the rod by turning the threaded collar after you unhook the rod from the wastgate arm, being careful not to twist the rod to the diaphram.

The auxilliary boost gauge can be any cheap air pressure gauge that will read up to at least 10 psi. The hoses that you can hook the gauge up to are any of the small diameter vacuum/pressure hoses attached to the intake body(near the coolant resevoir). Any auto parts store will sell vacuum hose tees in lots of sizes. Just cut one of these hoses and insert the tee. The hose to the new gauge goes to the third connection. I leave my tee in place all the time and put a cap on it when not needed.

Jumping fuse 27 to 30 will keep the pump running continuously and bypass the overboost pressure switch. Remember that the fuel pump cutoff is fairly violent and if you're just getting a stutter from inadequate fuel delivery, maybe your fuel filter is dirty. A bad pump or filter will normally be noticeable while accelerating and even cruising at highway speeds with little call for boost.

The knock sensor will cut boost in pulses under high boost conditions. It does not act on the fuel pump, but rather, it opens the wastegate momentarily. Then the turbo takes a few seconds to spool up again. An intrusive knock sensor is often the reult of over advanced timing or simply fuel of insufficient octane.

Go buy a manual and learn about this stuff to minimize guessing.
