This was installed along with an Airaid TB spacer and a K&N intake. As far as power it is kinda noticable (No wow factor!) what I did notice was the improved smoothness of the engines power curve. I'm pretty sure my fuel economy has dropped by at least 1.5 MPG and will verify this weekend and repost this review. I will remove each item one at a time to discover which one(s) caused it, although I'm pretty sure it's the chip and I did all this to improve my MPG's. I have 33 years experience turning wrenches and do it for a living (Took me 15 minutes to install) and must say the install instructions are generic and poor at best for a weekend wrench turner. I will give AA a A+ rating for their customer service.
