Sensor did what they claimed it would - improved low-end power. My HHR is 2.2 l & was very sluggish at low RPM, even considering it is a 5-speed. Car has noticeable improvement in accelleration, a big plus in traffic driving. RE: mileage improvement claim - marginal at best(ignore this part if you drive a Tahoe)Hwy is now 30.2 up from 29.9. Overall, is worth the cost & requires very little effort to install.
