Ok well every vtec car i have been in vtec hits harder then in my h22, even a b16. I have rode in a 5th gen prelude and vtec hits harder then in mine. I have an h22a and vtec hits a 6k which makes it a little smoother but it seems like it should be hitting harder. Like last night on the highway i was in 3rd just messing around and at like an 1/8 throttle and just let the rpms creep up to where vtec hits and when vtec engaged the car slowed down like the motor was under more load until i gave it full throttle. Car has plenty of oil, the solenoid has been cleaned tons of times, and oil the pressure is good. Could it just be that i might need to buy another solinoid.
