Not a lot of support for the Tec3 in the US. There are a bunch of good options now with good support. Haltech or Microtech would have the most support available and they both work great on the 20B. How do I know this? They've both been on my car and worked well. The Wolf 3D was probably the easiest to tune for a novice like me but there is not a lot of support for it here.

Charlies7 is correct though - go with what your tuner wants. It's the best way to ensure you get a good tune and are not responsible for problems if they arise. The tuner can't blame it on the ECU. Don't ask me who I learned this lesson

As for rotor housings, call Cam Worth at Pettit Racing - he always has a stock of rotor housings hanging around so you might get lucky. You can get new ones through Ray Crowe at Malloy Mazda but they cost a bundle.
