strapping that thing in and not getting it properly tuned wont do anything besides make your dash look pretty. if youre willing to spend the money itll take to get your car on the dyno so the vafc can be properly tuned, you may be able to squeeze out a few extra HP, it also depends on what you already have done to the car- you have to realize that having your vtec engagement point set to a lower rpm will NOT simply increase youre HP- theres a lot more to it than that.gregor said:
