> [Rotten Gas Mileage, no performance gain from Garrett chip]
I'd get the fuel pressures checked. There's a vacuum operated pressure
regulator that has been known to malfunction and cause rotten mileage.
I'm sure the ECU will compensate for incorrect fuel pressure (to a
degree) because of the Oxygen Sensor feedback loop, but it will then be
operating at strange points in the maps.
