I think there is something to the medium-heavy acceleration being better. If you take a look at my gaslog you'll notice a pretty steep increase a few tanks back. It corresponds to my change in acceleration technique. I used to accelerate in each gear to 1500 rpm's at a throttle setting of ~15 according to the SG. At the point where my FE took a leap up was when I switched to accelerating to 2000-2500 rpm's at a load of ~70-75% according to the SG. The TPS reads significantly higher with this technique. I should also note that I usually kill the engine and coast as far as possible once I reach my top/target speed.
