The OEM set up is a compromise and the tweak is just a wider compromise, but for better performance. We're only talking about a few degrees either way.
The goal of the procedure I outline is to end up with optimun timing for normal driving with a little more retard at max so you don't knock. Probably better for the engine.
The transmission is another issue, and with a tweaked APC and a heavy foot, you could probably go through a couple of transmissions a year.
FWIW, my 90 900t with all the tweaking that AI described is still on original tranny at 320k miles. Only major item has been headgasket at 235k and I attribute that to not using MB coolant until new gasket went in.
