TPS/MAPdot don't affect overrun... it's a function of TPS position, MAP reading, and RPM mainly. Just has to satisfy the requirements. I did notice you had DecelEnrich turned off above 29 kPa - this acts like a negative accel enrich - different from overrun. Bump it up around 100 kPa and might help drivability/save fuel a bit. Otherwise you .msq looked decent. Are you still runnin stock FPU? With those mods, you may be close to toppin out you stock injectors on stock pressure (have a datalog?). Otherwise I'd agree with before, with intake/exhaust restriction (plugged cat/muffler).
