No.

With the Cobra, Z32, Q45, J30, etc. MAFS, you need to "trick" the ECU at the very least.

Something to consider: &nbsp;The flow restriction of the stock MAFS (what I'm assuming you're worried about) is not that bad. &nbsp;It's about a 2" hole and it only lasts for about an inch. &nbsp;After that, the piping is much bigger. &nbsp;This will have almost zero effect on your rwhp. &nbsp;The main reason for changing the MAFS is to accomodate more fuel and more range (stock MAFS can't read past the flow of air needed for about 275 rwhp).
