It got the chassis dyno test which, from everything I've heard, is easier to pass than the static test. I wasn't concerned with passing just so long as the "Check Engine" light didn't come on right in the middle of it like it did 2 years ago. I had been battling that little orange light for the last couple of years at it would come on and go off intermittently. I finally bit the bullet and kicked down with the cash to change out the header pipe sensors. Should have done it long ago...I'll know better next time.
