(just for anyone who was looking for info - like me)

The Q45 MAF maybe bigger but since the Q is a V8 and has 2 MAFS and the air flow readings are limited with the Q sensor because of that. No one likes them (example.. Mckinny motorsports, heavythrottle, phase2motorsport). In fact the Q sensor does not work with late S14 engine, which is what i went though, i was getting a fuel cut at 5500rpm evertime i hit boost, EVEN stock boost! stay away from those Q sensors, bigger isnt ALLWAYS better

. The Z32 sensor is good for 500hp.

Hey, did you notice the date of this thread and that the point of the thread's having been started was addressed within a day and a half of the start of the thread? It was at this point that the thread was allowed to die, as common forum courtesy will usually dictate. What have you added of value to this?
