Infrequent short burst (like on an on ramp) will not influence your overall mileage a lot.
Slowing down to 65 or even 60 mph on the highway would easily get your mpg up.

Would it be better to use the vtec which kicks in at 4400 rpm?

VTEC wasn't introduced to be more economical, but to give more power.
Stick to the lower revs.
