Question 00 MAP and forced induction question

I recall a thread a few months ago, that I haven't been able to locate in a search about problems with the MY00 and forced induction. It seemed to relate that the MAP couldn't read the increased air volume and therefore didn't let the car get over 2 psi of boost. Does anyone remember this and if so, do they remember what the solution was? It seems like it was something simple, but I just don't remember. Thanks

Kent

A my00/01 needs a $0.12 4.7v zener diode on the MAP input wire and a RRFPR to run low boost. (actually this is apparently usable upto about 7psi)

you can either do a voltage clamp on the MAP so it doesn't send the signal of too much air to the ECU or you can use a bypass valve so the MAP never gets too much air

Rallispec posted the zener diode specs awhile ago. Ludespeed confirms this works like magic.

There are a couple options to get around the boost problem:
1-live with 2psi (not recommended, but free)
2-the zener diode (don't know much about this one, but I think Trey said it has voltage bleed)
3-JC Sports Torque Chip II ($250)
4-TEC II ($2000-$2500)
5-Split Sec voltage clamp (www.splitsec.com, $70)
6- FCD from J&S (Trey knows about it, $150)
7-ASR check valve ( seen at http://rave.stranger.com/Pictures/tmp/index.html , price unknown)

RRFPR is needed for all of them except #4
