Firstly is Gauge! And then its Wideband!

When you say riding? Is it a bike or trike?

If its a car then how you driving it? Is it cruising or you at WOT? A few more details will help.

10 is an okay AFR for WOT. You should probably fix a few things. Boost leak test. Fix leaking vac hoses. Get a tuning device. Fill out your profile. Simple things.

Its ok, im just joshing around LOL,

And if its rich under WOT thats fine, stock its pretty rich, so its safe, if you are adjusting via the ecu or flashing then you can lean it out a bit accordingly,

But if its just stockish dont fear, it is all ok
