Is this for the honda? Maybe a good idea to stop before you hit vtec engagement. Another idea maybe to get some parts to advance the cam or disable vtec. I know it varies from engine to engine how and what vtec does on an engine.
I had a geo metro and now a suzukie sidekick.Both cars I purchased 3 tech cam advance gear to drop the power band. This allows more shirt shifting and less winding of the motor for when you need power. I get 30 mpg in the kick with 205/75r15 tires and driving how I want with traffic. Tops out at 75 mph in 5th gear.
