Air:Fuel Help. Cannot Get it Rich

j par said
You know I'd like to say I have something to bang mine off to test it? I mean all I can do is really calibrate it and hope that it's working? And of course you drag race so you know watching the plugs is the biggest thing. The two should go hand-in-hand.
I don't like changing a part before I verified that it's the problem. I find this costly.

The original sending unit lasted a few years, and was pretty fouled. I used to do a ton of street driving and was always rich. It stopped sending a signal, therefore it was replaced. The previous sender when working seemed to match that of the plugs and the dyno testing prior to the engine being installed (+- 12.2:1 - 13.2:1).
