Do you mean discreet component values as in resistors, or as in memory map
locations, perhaps both ?

And back to one of the earlier questions, what is considered "safe" beyond
the stock boost, assuming that ignition timing is correct?

D'Amato got good results with only a boost increase, but at the moment is a
little risky because the overboost protection is gone. (The fuel pump can be
made to go off when the engine stops.) Maybe he he has gotten a lot of bang
for his buck without the more aggressive timing or higher rev limit. If some
overboost protection could be installed (and I think it can) perhaps this
would be a reasonable approach,  if not ultimate. It would use the stock
conservative timing and rev limit but apparently still give significant
performance gain.
