Do you need an ECU update from the dealer after you install it? Someone said if the car doesn't go past or stumbles at 4k rpms then it is your MAF. I just got an Induction service but that didn't solve it, although the car feels smoother and more eager to rev.

i replaced my standard maf with the updated one w/o the ecu update. i have had no issues yet. my standard never died but i wanted to have a back up since i had just put on a new 9" k&n and was unsure how it would react.

 

same here...I use the updated one and keep the original as a spare.....

 

Me too, and did not update the ECU after installing the new MAF.
