does 08 Mustang GT need a special tune w/ shorty headers???

[mmorningstar]

I'm considering FRPP or JBA or BBK Shorty headers for my 08GT and I wondered if a special tune was required due to the increased airflow, IE, does it throw a code from the downstream O2's seeing too much air too fast? Just wondering if anyone has input. I already run the Steeda 91 Octane tune with the 90mm MAF, etc.

Are you planning on changing the headers only? Do you still have cats on this vehicle? If you are going to only change the headers you will be fine. If a offroad xpipe is in your list of mods the rear o2 sensors will have to be turned off. What revision is on your predator? It will be displayed at the top of the main screen.

I plan on keeping the cats, just shorty headers, so I should be okay, thanks for the response.
