How can i get me engine to rev up faster?

easiest, fastest and cheapest way doesn't cost you a penny is to adjust the throttle linkage cable by removing all slack from the cable. By default from the factory they leave a little slack so that when you press the accelerator pedal you don't instantly fly right off the mark but gives it a slow control smooth gradual start. When you adjust the cable and remove the slack now when you touch the pedal even so slightly you will fly right off the mark without even a split second hesitation. The only drawback is you have to learn to adjust your driving as they can be a little dangerous if you push the pedal too quickly too soon you can end up rear ending the person in front of you because they are not as fast as you. You must learn to let them move ahead a little further as to prevent running into them. Also when you start you might end up jerking off of the line because you need to learn to adapt to the new way your car responds to your pedal as there is no longer the usual hesitation as before. Eventually you will get use to it. I am surprise nobody came up with this idea. Sometimes the simplest thing is the most effective and cheapest way.
