My CEL has been on for about a week now, first the code was telling me that my left bank was running lean and my first O2 sensor was malfunctioning.
I went ahead and replaced both O2 sensors, and my CEL came back on...now both banks are running lean! I'm now thinking that my MAF is bad b/c I cleaned it as soon as my CEL came on the first time.

Couple of questions:
-Where is the best place to pick up an inexpensive OEM MAF as I can't pay $400 for one at this point?
-What is the advantage to running a TT Supra MAF on my supercharged engine?
-Will I need larger injectors to realize the full potential of a Supra MAF?
-Also, if I go with a URD fuel upgrade kit, will their software allow me to adjust my ECU for the Supra MAF or will I need a SMT-6?

thanks in advance

1) Best place for a cheap MAF is the junkyard (96-98 Tacoma or 4runner will do)

2) The supra MAF opens up a bit of restriction on the front end (keep in mind the throttle body is still your main restriction before/after). It is able to allow slightly more airflow but I am not sure what the increase in HP is......by itself, not huge I don't think.

3) You should have the URD anyway....no need to go to injectors larger than that though

4) Yes, their software should work fine with the new MAF
