K&N Filter risks getting oil on the MAF element if you aren't doing a clean & re-oil absolutely perfectly. In other cars, we've seen more crud under the K&N that under a pleated paper filter too. Nod goes to pleated paper unless you have the throttle all the way open at high RPM's. The rest of the time, the throttle is the controlling restriction to engine airflow.
Your Pilot uses an array of exhaust gas oxygen sensors to trim fuel mixture, after initial guidance received from the MAF. A "performance" MAF will have little effect on mixture, as any changes it makes will be trimmed back based on the measured exhaust CO component. If the "performance" MAF slots in where the factory piece lives, there will be no change in airflow either. Unless there's something magical, save you money.
As far as performance chip, go for it and report back your results. In my limited experience, the only available parameter for the chip to adjust is ignition timing. To get the performance boost, you'll need to buy premium fuel to protect the engine, or enjoy the knock detection system pulling that spark advance back out as quickly as your performance chip tries to put it in.
Want better fuel economy? the factors that affect mileage most are diametrically opposed to "performance". Enemies of fuel economy are the pedals. Drive like you have a raw egg under your foot in your right shoe, with gentle throttle inputs. Brakes are death on mileage, since they waste all the kinetic energy you've built up, turning into useless heat. Think about driving like you have no brakes -- anticipate traffic speed changes far enough in advance that you can avoid using the wide pedal until the car has slowed almost completely to a stop on its own. Preserve that inertia, and you'll need less energy to bring the car back up to speed. Also, do everything you can to keep the car in top gear with the converter locked, with the engine spinning as slow as possible in that mode. Think 48-55 MPH and that gentle egg-filled shoe. AC is off unless it's needed too.
My car gets slightly better fuel economy if I fill with premium fuel, but at the current low fuel prices the percentage improvement doesn't justify the percentage cost increase. Using regular, My trip computer says I'me getting an average of 24.5 MPG in local driving. The calculation at the pump is about 1 MPG less than the computed value. Highway use only, like on our little Thanksgiving jaunt to the bay area, showed 27.5 on the trip computer, and again about 1 MPG less when calculated at the pump. I keep the tires at the recommended pressures, use synthetic oil and trans fluid. And drive like there's a raw egg in my right shoe.
