Being light on the throttle and letting the revs go higher is horrible for BSFC. I would keep the revs well below v-tec when shifting, like 3000 rpm, and keep your throttle opening high, like 75%. Remember that it is well documented in this forum that brisk acceleration isn`t a bad thing for fuel economy (provided that you are not accelerating briskly to the next traffic light 100 yards away!). Think of it this way: you can be super light on the throttle and slowly accelerate onto the freeway, taking 30 seconds to get up to speed at a horribly high BSFC, or lug the engine (shifting at 3000 rpm in your case) with a 75% throttle opening and be up to speed in 10 seconds at a much lower BSFC. Sure, it burns fuel at a faster rate (GPH) at 75% throttle, but you will be at 75% throttle for a much shorter time.
I actually plan on testing this with my Mazda Tribute V6 soon. I plan on driving a piece of road with a few stop signs late at night when nobody is around. On one run I will accelerate slowly to a speed of 60 kph through the course of the stop and go drive. On another run I will accelerate briskly to the same speed. I believe that economy will be better on the `brisk` run. But I guess we`ll have to see.
