I think you've misinterpreted what I meant. The piggyback fuel volume limit is defined by the largest constriction in the hardware, be it health or the combined upper/lower limits of each individual component. Two people could have the same mods and piggyback, one person with trims at 20% and the next person pegged at 34%.

I didn't know that the FF kit also came with a flash. If so then you shouldn't have an issue with OL fueling. It seems like they have adjusted it moreso with their latest flash to keep trims closer to zero.
