Seems to be pretty good, but would i be able to use my stock 02 sensor, or do i have to weld in the bung?

We have a 4 wire narrow band 02 sensor don't we, on the upper 02.?
"My late model vehicle uses a wide-band sensor. How can I use the E-W-S on my vehicle?: If you have a 91- present Honda, a new Subaru WRX, or other vehicle using a wide-band sensor, don't worry. You can still get the benefits of our DEW System, by fitting an auxiliary sensor. We sell a heated (4 wire) sensor below for $50. Any exhaust repair shop can fit a bung (threaded fitting) to your exhaust system for about $20. The same procedure is needed for the fitment of an aftermarket wide-band A/F meter, or for the use of other narrow-band meters (such as the Autometer unit)."

that kinda looks like a less fancy narrow band a/f meter
Its says right underneath it that its a narrow band:
"I've heard that you need a wide-band sensor to tune your A/F mixture. How do you do it with a narrow-band sensor?: Although an expensive wide-band sensor is needed to make precise changes in mixture (such as those made when programming an ECU fuel map), narrow-band sensors can provide enough information to warn of excessively lean conditions under boosted applications. Racers have been successfully using the voltage output of narrow band sensors for over 20 years, to prevent costly engine damage. Our unique display provides an Early Warning System that is not even provided on many wide-band units. For this reason it makes an excellent supplemental system for a wide-band meter, as well as a great stand-alone system."
............super 60 on its way
looks pretty kool
and no the upper o2 is 1 wire.
