if your not using paint with the eye on, it will delay the bolt if it doesnt see paint. if you turn the eye off, it will delay the bolt whatever the c-on setting is (i think, been a while since ive read an eblade manual). but if thats high it can limit the rate of fire. with paint and air, it will more or less shoot as fast as your loader can feed it.
also with a TT tol setting of 42% you might find your trigger is very bouncy. depends on how your trigger is set though. i think i ran mine at 40% band and 12% tol.
i also couldnt get my c-off below 28 without having dropoff, but i dont know if the mq2 will let you run it lower or not.
