All (or at least most) of the high or low signal faults should be turned off. The reason for this is the harness is wired with only a few common 5V and ground wires that feed everything instead of having dedicated lines back to the ECM. The performance faults are still active so we can detect issues with the sensor, but these high/low faults should be turned off. The main reason for this is to simplify the harness since they use larger gauge wire than the factory harness (it's already ~1" in diameter at the largest point).
What remains unexplained at the moment are:
- VSS: why am I seeing 158mph all the time?
- Baro: linked to P2227, do I need this? Where is it?
- IAT: if this is in the MAF, how will it work properly with a blow-through setup?
