FAST Wireless Air/Fuel Meter Kit

I've been following this tool for some time now and wanted to reach out to see if anyone has any experience with this wideband kit or something similar.

It is expensive. However, I have two carbureted cars and several friends that tune and maintain theirs. So it would be put to use(I almost talked myself into it)

I like that you can get readings from both cylinder banks, capture the information through the rpm range and have historical data during the tuning process.

Thank you and I look forward
