The only option I know of is Twisted Tuning

Know if anyone who used it or used it, any reviews on it? Their website is pretty lacking in information and gains from their tunes
I tried to reach out to them a few months back and haven't gotten a response back as of yet.
From what I've seen, the 03-05 ECU is on lockdown. You can't get into it. The 06-08 might be able to be tuned. I have also heard that you can have a 06-08 ECU vin flashed to a later year. If that is the case it would be worth looking into however, we are still not sure if we can even still get tunes or whatever.
Personally, I'm over it. It's been too much trouble trying to find tuning and the supporting mods that go along with it. Just enjoy the car as is, toss on a CAI and some new mounts and call it good. The money one would have to spend to do tuning , vin flash, etc, could be used towards a different platform swapped into the 6 that already has all sorts of support.
Don't get me wrong, I love my 03 but the cost of even forged positions are out of this world for no hp gain. Not to mention that even Mazda has discontinued a lot of parts for the 1st gen. Some of the things they have discontinued are major parts of the car smh.
