Yup, over 10 mpg.

It was such a big change because the mods permitted the car to operate in lean burn 100% of the time at 80 km/h, where without them it felt like it was on the edge, moving in & out of lean burn at the slightest change in throttle position to maintain that speed.

In other words, the % change might have been less impressive if I'd tested at 70 km/h or at 115 km/h (either fully in, or fully out of lean burn for both A and B runs).

I didn't plan it that way, but it was interesting to discover. I tested at that speed because it's the highest posted limit on the secondary roads I usually travel.
