built-in boost valet switch? was: re: MAC11B problem?

"valet switch" for the boost level?  I'm thinking one would be able to
put in a switch for this purpose.  Would this work on a chipped ECU?

You can achieve pretty much the same effect by interrupting the WoT
switch return to the ECU.  Same symptoms as a defective (a.k.a. Type
1 - they're all bad) throttle body switch.

As a general guide - if your throttle body switch has a visible seam
running round it looking like it would separate into two halves - it's
broke.  The Type 2 cover slides completely over the body of the
switch - no visible seam.
