Default Who has a compression reducing head gasket on their AAN?

Hard to remember the last time I drove the car before it was put in, but it seams to have made a really noticable difference in both off-boost and on-boost power.

Default I do

definitely lost some low end, spool up is later than before but hard to pinpoint exactly how much.
