Hondata

the problem am having is that my car was tuned by a hondata dealer 1 week ago and the car ran fine on the dyno af ratios were perfect,now couple days after am on the road the car feels like shit i look at my wideband af guage and it's reading so rich that it went blank (-----).
but was fine the day before that. what could be the problem?

It's really hard to say without the bin file and a datalog. I would suggest takign the car back to the tuner so they can take a look at it.
