hey guys, i'm looking up parts for my new 98 GSX (YESSSS FINALLY GOT IT) and i came across a "wideband" it looks just like a normal o2 sensor only about 200 bucks more expensive, i see that you can read more things on it but do you really need ot pay that kind of money for it? or does it serve another purpose?

 

yes, get it. you will be able to tune better. it is recommended for any FI'ed vehicle.

 

youre not ready for it and have no use for it yet. that comes after bigger turbo/fuel upgrades
