Default Accufab causing problems?

Hey all I have a 2000 Mustang GT, which I recently just had a 62mm Hellion Kit installed and tuned. However when I had that done, I had the stock tb and p on the car. This weekend I installed the Accufab 75mm tb and p, and now the car is running a lil rough. When I am idleing my a/f ratio is 22.4, which seems pretty high. Also when accelerating the a/f ratio tends to go low then high then low...repeating until it settles on 13 or 14. I was just wondering if there is anything I can do to my Innovative Wideband A/F controller or with my XCal that would correct this? Thanks for the help.

Once you get an FI tune you DO NOT ADD OR DELETE INTAKE OR EXHAUST MODS without an immediate dyno tune.

If you are seeing 14 A/F at WOT, PARK YOUR CAR. You are about to asplode the whole damn thing.

+1, couldn't have said it better; especially with a turbo since they are more sporadic than superchargers.
