I did a search and came up empty.
I have the bungs in the collectors and am ready to take tuning to the next level.
What's the best way to go?
What all is available?
What are your experiences?
Any members sell what I need?
Sorry for all the questions.
Thanks for your responses.

I use a LM-1 meter... I have just the single wide band sensor but they also make a double(but I think they have trouble with that one)

One tip, if you don't have an exhaust system behind your headers, the oxygen sensor in the collector will get backflow outside air at idle and low throttle positions making tuning idle and driving in the pits useless. A collector extension will take care of that, somewhere around 14" or so.
yup, and leaky collect extensions will make for a very shakey idle idle reading. Mine would vary up and down between 13.3 and 19 at idle wicked bad but once i got a real tight exhaust system, it was much smoother without any of the wild fluctuations

I found mine at part throttle would read substantially leaner with the header cutouts open than closed, and I had the cutouts located 1.5' after the o2 sensor which was at the collector. So I am wondering if that's due to outside contamination or if my exhaust is really that bad!

Where is the best place to put the bung in a full (except tailpipes) system?
I plan to get a LM-1 this winter.....

I'm running the FJO racing product sensors, dual band, data logging, (analog/digital) gauge... www.fjoracing.comI have my sensors located in the collector. I've heard the the NTK sensor will last a little longer than the Bosch when running leaded "racing" fuel. The attached plot is when the unit was first installed. I'm rich at WOT, and had a O2 sensor that was "lazy" and has now been replaced. It was interesting to see how lean it spikes when first stepped on, need to richen up the shooter or change the pump setting (carter carb).
