60 psi of air pressure!!!! I was having issues getting any rpm's past 2500 after replacing the accordian hose, During the hose installation I thought I would be clever and clean up stuff, naturally i went with carb cleaner, :nono: i forgot that the AFM does not like this... So I filled it up with glass cleaner and was blowing it out using my compressor, then, POP the top came flying off!!! I finished cleaning out the inside with Q-TIPS an gorilla glued it back together, scared the crap outta me when that thing cam off there with a big POW. Its pretty simple inside and fairly easy to clean. I'll know if it worked in later tonight and post back with results. I haven't checked dealer prices yet for the AFM sensor but an betting they are nice and High :naughty:
