Thank you for the positive feedback, makes it worth while for me to stop and take pics all the time and document every step of the way, the gauges are so accurate and so sensitive that they show changes otherwise undetectable to the human eye, ear, or nose. For example barely moving the idle mixture screws like 1/16th of a turn changes the AFR by over half a point without even changing the RPMs, I don't want to start World War III or nothing but I am willing to bet many of the tune by Long Screw Driver To The Ear mechanics of yesteryear were most likely way off and either not getting the fuel economy they could have and or leaving plenty of horse power on the table
