No, you dont get a big power boost...you get a moderate spike in power...nothing "big". In fact, not all vtec motors are desinged to use vtec as a power adder. The HX vtec, vtec-e, is a way to increase fuel efficiency, and in the sohc (d15b,d16z6/y8) motors vtec is very minimal power spike AND small fuel compensator.
Yes, my car does have vtec. D16y8 sohc
Do you know what vtec is?
