Probably the only tip I'll add is to turn off the AC while accelerating and turn it on when engine braking (DFCO). Remember that if you're decelerating rather than coasting, you're better off in gear and engine braking since it will cut off fuel flow (generally above 1800-2000 rpms to initiate, but continue down to 1000-1400 rpms during the decel). You'll still be turning the energy, so it will turn your alternator, water pump, and AC compressor for "free" by converting that forward momentum you already paid for into mechanical energy.

Whatever you do, avoid accelerating with the AC on. Your load will be about 5-7% lower on acceleration at the same rate without it.
