Ya I just swapped to a 4.3 FD, but my speedo was still inaccurate even after changing the ratio in flashpro, Vit had to adjust my speedo by 8% which is another setting in flashpro. But my speedo never worked weird, just read a little lower than I was actually going. I would try one washer and see how that works for you.
