I agree but I didn't see any noticeable difference in the hp or torque. If anything I thought acceleration rate decreased.A loss of 1 mpg isn't that big a deal....is it? What about the increase in horsepower/torque? Remember...we're driving a high-performance sports car guys! Why are we getting upset over incidentals, like 1 MPG? Look at the benefits of the mods we make usually rated by horsepower and torque numbers, which are much more beneficial to us in the long run!
