first of all if your car is stock the thing that you are feeling before you hit the rev limiter is your secondairies on the IM opening up. You don't really feel/hear the vtec kick in with a stock gsr. I would get a new tach if i were you or fix the one you have. Hitting the rev limiter isn't all that good for your car and plus you don't get the most power at redline. :no:
