Just bought my 95 del so dohc v-tec. Can't stand the high revs on highway speed. Feels like it needs a 6th gear. Any ideas how I can adjust to lower rpm, through computer? Will tranny change help? Need better gas mileage like my standard 95 civic coupe. Going from close to 50 mpg down to 30 mpg on del so. Don't need the extra power. I drive about 250 miles a day, so the mileage does count. Just trying to increase mileage if I can.
