GH turbo upgrade tune question

[76FoMoCo]

So I have full bolt on's and the GH turbos are going in today. Matt has sent me a file for them and I also have a file from Brad for everything except the turbos. So my question is can I still run Brads tune and will the computer account for the larger air flow or will I need a new tune from Brad? I have sent him an Email but have not seen anything back in a while.
my thoughts would be the WG % would just go down and the commanded boost will stay the same.

his wife just had a baby so his availability is even less than before. Personally if I were tuned by both tuners I would run Matt's tune until I heard back from Brad.

I had a conversation with Matt about this when discussing parting out the SHO.

Without going into a lot of details, the answer is no, the car will be extremely unhappy. If Gearhead sent you a tune designed for the bigger turbos, run that one until you hear back from Brad as Lee said.

There is more than just flow involved as the wastegate is also adjusted. Things will be very unhappy.
