Yes, that's true. If you enable this option, it will use batch fuel/wasted spark right after the first sync (until fully synced):

without complex piping your only sensing the MAP on one throttle and that fluctuates badly.

autotune is trying to catch the correct values. Autotune in TunerStudio often tends to "saturate", when there's a big difference between actual and target values.

How did you managed it? AlphaN algo ?
Speed density + TPS-based VE table + TPS-based advance table. But it also worked with pure speed density, just not as good as with hybrid MAP+TPS-based setup. As for the MAP, I've enabled option "Use minimal value of = 4" (for 4-cyl).
