You could go to tuning software that has 2 bar density and some coming out with 3 bar soon.
Well anyway My point is with software you can just about make the engine do what ever you want. True it is a little harder but if You call around you may find a shop that has software for your year as the high dollar stuff is not vin specific it is vehicle specific. You can have them tune so that MAF is fooled all the time till you change it back and you should be able to do the same with sensors and basicly you are just fooling the PCM into thinking the stuff is there and working and it is not. I would think a tuning shop could help and not charge much. The sensor is reading the oxygen left in the exhaust which of course is telling the fuel inj. if it needs to lean or richen up everything. I would ask a tuning shop for help so you do not have to spend money on buying software but, if they charge like 350 to 450 then you need to buy the software and learn to use it. You can get a real good setup not with everything but for $500 to $700 then you do what you want when you want. They are not hard to learn to use.
