The DFGT LUT is intended to work at 100% FFB. Only the "NoClipButStronger_recommended" one needs 50% FFB! So rack it up as much as you want (well up to 100%) To the noise: it might be the very very first value OR the dampening! You really don't have this?: btw: ff skip steps actually REDUCES the Hz of the wheel so let it be at 0!
