Default Who has tuned their AVCS system, Who Wants To?

For the past few months I have been reading and trying to understand Subarus AVCS systems a little better. I believe I have finally come up with a good system to tune without a dyno. Using a combination of EGT, Exhaust back pressure pre-turbo, and road dyno software. I have managed to increase power quite a bit in the low and mid range. I have also found turbo lag to have been reduced. I'm wondering if anyone else here in Alaska has been messing with this part of the tune and what sort of results you have been finding. I would be happy to share research, results, and tunes with who ever else is working on these tables. FWIW larger than stock turbo owners have the most to gain with AVCS table adjustment. Stock turbos can also see gains it seems but not as much from what I have found so far.
