Rich,
To be sure run it on a dyno to check the O2 that takes all the guess work out of it.Are you running the stock air filter?

I think one dyno pull to check O2 is cheap enough for peace of mind,IMHO there too lean to start with and even though its been said the ECM can adjust enough I like to see someone's O2 after they change a air filer or exhaust pieces.
