Just a remark...
I noticed driving yesterday that the Integra is pulling hills with relative ease lately. The data confirms it -- on hills before where I would scrub 10 mph at constant throttle, at the same input, the car only loses around 2 mph.
The intake air is the same (120F) and the FE has increased
The outside temps are much cooler, but I haven't been using the A/C for a while. The only thing I can think of is a recent oil change, but I've had a few trips since then without this kind of power. The humidity is up which could aid in the combustion dynamics, but otherwise, I'm stumped.
