I've been letting the PC Autotune at it for a couple weeks now. Damn it's running well. It feels so good that some of the character seems to have seeped out, if that makes any sense. If anyone's looking for a map for a 535 with ace air cleaner, Otto trumpet , Motad exhaust, squish mod running at sea level-400 meters on 91 (that's 80something for US crew)...
