Default Line Pressure on Trans?

My buddy who used to own a GTP was telling me there is some type of revised calibration for our cars that upped the line pressure and made the transmissions much more durable. He seemed to think this was something that dealers could do. Anyone heard of this?

For that matter, what is the consensus on upping the line pressure? Good/bad? Are people doing it via the computer or via shift kit? I'm just looking for ways to make my daily driver a little more reliable.

That is done threw a tuner. Mine is upped a bit. Adding a shift kit will make your shifts faster and firmer, adding more line pressure will speed them up a bit more as well as firm them up. I see you are about a hour south of me. I have HP tuner and could make changes to your PCM if you wish.
