EVO and Protomotive uses them. They are not just replacemants, you need software to use them.

Need to reflase the ECU. I have had my issues as all of us have with blown MAF's. Mike at EVO hooked me up sent me one out so I could make a 3 day track event about 4 weeks ago. I will tell you not one problem and I was not babying the car at all in fact I bounced off the rev-limiter a few times not one PSM, ABS no Limp Mode etc. Just came back from Pocono Raceway for a 2 day event ran the car very hard for both days no problems. So far it is bullet proof!

I have the Hitachi MAF. Works great!!! As others have observed, a new tune is required. The good news is that, with the Hitachi MAF, EVOMS can extract additional power with the new tune.

Interesting that Proto is also using the Hitachi MAF. I know that Todd has customed designed a modified Mustang MAF for most of his cars (Proto charges 1K for this MAF). How does the Hitachi compare w/ the Proto MAF, and what is the cost?

I am still waiting for an EVO (or other vendor) to offer a line-item
product: "Hitachi MAF conversion (hardware and tuning) $XYZ"

It sounds like the added sensitivity/range of the Hitachi MAF
allows a tuner to get more power. Can anyone say whether
this would be true for all 996tts?
thanks
Joe W.

It is. You can calibrate them any way you like. The cost of the MAF is not 1K, closer to $300 for the MAF itself.
