| I wouldn't bother.  The last thing you would want to do is remake a part

| have no benefit over speed-density systems except for OEM production
| where the air mass flow sensor can compensate somewhat for production
| tolerances.  They are expensive, fragile and require more complex
| calibration.

The advantage to MAF is that the computer can automatically adapt to engine 
modifications like a less restrictive exhaust or heads that flow better, 
right?  SD requires that the volumetric efficiency table be updated any time 
mods are done to the engine.
