If you are at 10% higher load for 12% lower revs you apparently gained 2% already plus whatever the higher efficiency at higher load may bring.
I would be surprised if it brought you more than 5% net gain. And that's just cruising at speed. It will not affect city driving at all.
If you spend 80% of your miles in the city, you'd get just a 1% gain all over.

The effect may get bigger if you reduce air resistance or highway speed, as then the load decreases and will be ineffective in the OEM setup.

The higher load also means less need for and less effect from P&G.

Colder weather will have a big effect. Is it colder in Toronto now than when you used the OEM setup? That's the likely answer then.
