what MAFS are you running in your RB's. i didnt get one with my swap, so obviously i need one. i found a maf from a 91 Q45. this gonna work for an RB25? im already getting a throttle body from this guy for my greddy intake manifold. was just wondering if i should get his mafs from him too. thanks.

you should be able to use another MAFS as long as you can change the settings with something like an SAFC or other ecu piggybacks.(if you don't have such thing i don't think you can plug any other MAFS cept for the stock 1)

either will work with the PFC, q45 is usually cheaper and can meter slightly more.

i am running a gm blow through maf on mine and it wors great, that way you dont have to have the maf b4 your turbo and you can pretty much make whatever style inatke pipe you want (assuming you are running an intake pipe)

If the MAF is bad, can it cause a choke on high gear(4th-5th) rolling about 60-65mph and go.

No if the MAF is bad you can not rev past 2500 RPM.
