not to thread jack I but what code are you getting for your MAF?, i scanned my car and mine came up as signal to low. I never cleaned mine since I owned the car, should that help or just replace it?. Also I am going full stage 3 in about a month or so I dont want to buy a new bosch MAF, and then pay again to switch to the hitachi. If I clean it a still get a code and decide to get the hitachi with the wiring will it run fine even though my cars a 2000. Or will the ecu have to be tweaked for the hitachi.
