So im on the fence on which one to get. The defi tells you to tap into the wiring on your stock oxygen sensor while the uego comes with its own sensor.I know the uego is used by alot of people and alot of people like it. How accurate do you think the defi a/f gauge is? Anybody using this?

this one right here, also you can use this without the mutli link right?

well im guessin the defi is a narrowband since it uses the stock o2 sensor which would kind of make it useless. the uego uses its own sensor that works on a 0-5v range vs a stock narrowband which works on a 0-1v range which is basically useless as far as getting a proper afr and for tuning purposes

stock oxygen sensor is an on/off switch. Not a way of getting accurate A/F

I noticed improved response and power after installing the AEM and setting it to emulate the stock signal. Like a noticeable difference.
