Drive slower(acceleration and top speed) and use the highest appropriate gear. Use the min. acceptable octane (87). You'll get better combustion and power than a higher octane. I know these seems too obvious but there isn't much else you can do but perhaps use a thinner oil like Mobil 1. There's a wide range between 20 and 40 wt oil. Some 30wts are thinner than others and M1 is one of them. If you have a manual, you can also pick a gear oil that's on the thin side of spec like Torco.

It would depend on the intake, MAF position and how much leaner it's actually running from the intake. Hardly foolproof but the right combo could do something as you are running a leaner mix. Part of how a cai makes power is gettimg the A/F right at full throttle by leaning out the mix (stock is rich here) but often leaves things a bit lean for normal driving. Hence better mileage but less power at lower throttle positions and low rpms. Not what I would want if I was trying to take it easy.

Never let your RPMs go above 3000. Unless you're in top gear, never cruise at more than about 2250 RPM. If you start exceeding that, upshift. (On the bottom side, never let the RPMs get below 1800 - downshift)
