To Stillen: I searched the thread but couldn't find it, are you using the V-3 SCi-Trim or the V-3 Si-Trim?

Edit: Reading through the thread I was kind of surprised with some people wanting "speed density" air measurement.
This is less accurate as your not measuring the actual air mass, but using a big lookup table and some sensor inputs to come up with an air mass estimate.

Additionally for the person asking about the MAF before the supercharger and the temperature difference. This doesn't affect the air mass, as the same air mass still flows passed the MAF, just at a lower temperature/higher density. If the MAF can deal with the higher flow, the measurement of the mass of the air is still correct. Where it does affect is that hot air can lead to knocking, however you can tune for this by not using too much ignition advancement. And the use of their air-to-water intercooler also reduces this as much as possible by cooling the air back down before it enters the cylinders.
