I guess the VE constants are having an effect as well.....food for thought?
Also was doing full load runs with knock phones and a tech watching the exhuast for detonation and tuned the full load timing. Those knock sensors can now be detuned to register real knock.
This particular car was getting about 11 to 12 l/100km on the instant readout at 100km/hr.
