That is the action of stock torque drivers and the angle of which they open and close. They are designed to function that way. It basically gives you good high-rev power to take off, then settles to a lower, more fuel efficient RPM. I like to swap them out with straight-groove torque drivers like this one: SSP-G Torque DriverHere's a video how to install them: |

And does an aftermarket air filter give you extra performance ?
