Took just a couple of minutes to install. Can't really "feel" the difference but I didn't expect to be able to feel it as based on reviews the HP difference is not as great as claimed in the ads. But, when you add the chip, plus an Air intake modification, better plugs and modify the exhaust I expect about an overall 10% increase in HP and the chip is one part of that. Still worth the investment from my perspective.
