FMF Programmer Tuning Question

Will Fine Tuning My FMF Programmer Really Make A Difference? Ive Been Running It As It Was Shipped Since I Installed It. I Have A Q4 With Flapper Mod, AIS Removed With EXUP Gone W/Servo Eliminator.

yes and no.... i didn't feel a whole lot of difference when the values were set correctly. but when they were set bad, ya a huge negative difference.
