Putting in a wideband sensor here in a min and I'm wondering if I watch it while I hit the 100 shot if it will tell me if I have the correct jets in or not? If it reads lean on the 100 shot that would mean I am spraying to much n20? and if it reads rich I am spraying to much fuel? Or is reading plugs the only way to go?

reading the plugs is the only way to truly tell what is going on inside your motor a wideband is great for your afr but it is going to read the whole motor, plugs tell you by the cylinder so both are needed to keep it safe but the plugs are the true indicator

Its hard to say. If its going lean or rich it could mean a lot of different things including but not limited to correct jetting. Wideband will tell you if the engine as a whole is rich or lean but will not tell you the whole story. Its an average of the cylinders. The absolute best way would be reading the plugs.

Well if you have a plate or single nozzle system, and you see one cylinder is hotter than another, what can you do about it? You only have 1F and 1N jet to use and they'll effect all cylinders, right?

You could run a colder plug in that one hot cylinder without a problem.

Run the car on motor; note and record AFR reading while doing so.

Start with the recommended jetting; note and record afr reading while doing so and doing a proper shut down/plug reading on plugs.

Once you can make a visual link between your plugs and the recorded reading on the wideband then you can surely tell what AFR is what in accordance to your motor and what it likes and wants.
