Style chooser

Dear all,
I've been bothered by this for quite some time, as far as I know,
ignition advance would mean moving the ignition timing further away
from BTDC and retard would be getting it closer to BTDC. After
referring to most of the maps uploaded here, I've noticed that most,
or rather all the maps that I've seen had their ignition timing
retarded. I've sent my car for dyno tune recently and the tuner
advance all the timings from 3-6deg. I gained only about 2hp with
this...
