Is there any other symptoms the car is having like rough idle? Have you been smelling rich unburn fuel? anything like that
I would first narrow the problem down before upgrading anything.
like clean2g said, an Air fuel meter isn't always accurate.
with 300hp as goal I don't think you would need the wideband 02 just yet, if you are on a budget you can spend the money somewhere else. However wideband with logging capibilities is pretty nice to have for tuning.

Don't take it just anywhere unless they work on DSMs. the last place I took mine to when I had a problem with it was a local garage, told me it was the spark plugs and probably needs a new 02 however they told me they don't usually work on the turbo DSMs, Then charged me $60.00. Later I found out it was a boost leak.
