Default 02 wrx and MAF limits

Hi i have heard that the 02 wrx ecu MAF pegs out at 4.69 volts.
i am reaching 4.7 volts with plenty to go while tuning with MAF mode and utec do i need to switch to SD? is this true that it pegs out at around 4.69 volts ? thanks

Mine reads 4.9-5.0V all day long in my utec logs... stock MAF is 0-5V so you still have plenty of room left.

Thanks man. was told the stock ecu has a limit but was not sure how that related to the utec. also is it worth switching to SD if everything is running fine with MAF tuning. am running a VF22

if everything is running well you don't need to change to SD... there are alot of good threads about using SD so depending on what you need/prefer you may want to read up on it.
