I do know that the MAF in the Boxster is made of different materials than most MAF out there. Therefore, it MAY be that you will not obtain "normal" responses from chantes like you made, as compared to other MAFs you may have worked on.
Are these EVO folks of no help here? It seems THEY should be the ones troubleshooting this issue instead of YOU and with THEIR nickle, not YOURS.
Do you have a friendly parts dealer than can sell you the MAF with a money back guarantee?
