well, i dont have a trinity, but i would think it would be similar to the predator.
I would leave the curves alone, unless you're dynoing it.
Do you mean throttle boost? if so that helps reduce the lag/delay. i'm running 12% on mine.
When you adjust rpm's there are a few places to do that in different ways. you can adjust it for top rpms (driving) and for "park" ( when you rev it up for sound,to hurry someone up, etc...) and there is another spot to change idle rpm's- i think thats the one you were changing. hope that helps a little.
