You are some piece of work. Lets think about this one really really hard. You stated you are pegging the rev limiter a lot when you run. HMMM, I would say you have PLENTY of power in the upper end. You just run out of upper end. You need more RPM, not more power. Take a few courses in mechanics and get a bit of wrenching time under your belt before you start B****IN and moaning about the advice you have been given.
If you hit the rev limiter it means you are going fast enough in that gear. Grab another. Dont have the grunt to pull that gear? That is not high rpm power, that is mid range power. The chip MAY help you there, but dont expect anything drastic. A cam is probably your best option here, coupled with a supercharger would be a drastic improvement.
Its 6 of one, half a dozen of another. Regear to bring the gearing to where your engine can propel the vehicle at its fastest potential or stroke it and set it up to rev higher in the gear, thereby giving you more speed, or give it more low to mid power so that it can pull the taller gear, thereby giving you more speed. Its just how deep is your wallet.
Word of advice, watch your tone. You are getting FREE advice here. You dont like it? Go away. Simple as that.
