Under WOT conditions, another circuit opens up in the box, and timing advance falls to 1 - 2 degrees.<br><br>As for why only 9 degrees, its a design philosophy. More timing advance, the more likely you are to blow a head gasket. So TST prefers to make most of its power with fuel, versus advance to help keep the head gasket glued together.<br><br>Rod
