If Trims start to go above 25 that means that that you require more fuel to bring it down.

If the trims start to go below 25 that means you have too much fuel going in.

Is this correct?
Yes correct. The car is setup so it can add up to 33% more fuel (trims = 50) or reduce fuel flow by up to 33% (trims = 0).
Ideally trims would be 25 all the time where the perfect amount of fuel is being added but obviously many scenarios must be covered. Full throttle vs idling.

If your trims can't adapt far enough for your setup then you need to alter the fuel scalars in the back end flash.
