Kinda why if I don't see before and after numbers I keep moving on. Same bench before and after and you compare to what you see on your bench. It takes me less than 5 minutes to check intake and exhaust calibration and I do so before every different head goes on my bench. And I'm not even selling anything, I just want to know for myself. LOL
