I just got back from another spin
I did notice the sputtering only this time there was a hissing squeaking sounds with it
when the sputtering stped the noise stoped, is this a leak issue?

I had an issue with a hissing sound almost a loss of power when I hit the gas.  My engine did throw a code of running to rich or too lean.  The problem was that my turbo inlet pipe that i had replaced earlier came loose.  My O-Clamp came off and there was just that "BOV" sound.  Check the turbo inlet pipe that could be the case.  Let me know if this helps.
