that is not true, my friend had a civic type r vtech and his car was hella fast. everytime he cranked vtech, my head flew back to the seat, and i can barely sit up. but his car was not stock. and it was only a single cam. he had HELLA VTACK! so i have some questions..... if your car stock??? also, you need to upgrade to 1.5 inch exhaust, and take off your intake.. run open intake manifold for more air. you should see an improvement.
