Help I'm lost on what to do!

[FORZDA 1]

It started running crappy on my drive back from poland in the heavy slushy snowy autobahn and the MAF was my first thought....and it was dirty covered with road grime and salt that was sucked thru my fujita CAI (which is why I got the cobb short ram a little bit late tho) so i bought a remanufactured MAF thinking it should still be good but maybe it isn't. sounds similar to what cangelo went through..

It's not impossible, but I would do some troubleshooting rather than parts swapping. Cheaper that way and you learn more about your car.....

troubleshooting is what I have been trying to do but being over in germany with a us spec car sucks....the auto shops on base dont have anything I can use...ie a scan tool, vacuum pump. and the german shop tried to tell me that they dont have a german car to compare the mazdaspeed to and I felt smart telling him "yes you do...it is the mazda6 mps to you"...sorry just ranting!!
with having very limited resources at my disposal what would you suggest?
I want to get this fixed and really prefer to do it myself

Well, it sounds like it's tough going for you there. Without at least a few BASIC tools that ANY auto shop should have, you are stuck with the parts swapping strategy. Just consider what parts can cause either an actual overboost, or an "indicated" overboost. Well, if it is actually overboosting, it could primarily be the wastegate actuator or the turbine housing itself or a remote chance it is the MAF sensor. There is also a possibility the MAP sensor is screwy and indicating more manifold pressure than actual.

I think your best bet is to buy yourself a Dashhawk from your favorite vendor and use it to help you diagnose this problem and otherwise keep tabs on engine operation/performance....

The DH can tell you the MAF voltage, MAP voltage, boost pressure, etc...
