tbh most fd,s are prone to on off throttle jerkiness often made up up of lots of little things had it on pretty much all fds ive had to differing amounts. however on my old build i had completely dialled it out though lots of little upgrades some of which youve done. heres my list.
diff mount poly bush - black ones if you can find them.
full black poly bushed every suspension arm and fit new pillow ball bushes
nylon/solid plastic engine mounts
re wing gearbox brace (banzai one just as good) its rubber bushed so you get no vibration rumble inside.
you def have to get the tps position, air correction screw,idle and dash pot all setup perfectly for the slowed transition from on to off throttle.
i actually fitted ohlins dfv coilovers on mine as well which softens down the cruising suspension so its not jaring but firms up nicely when pushed.
my blue 7 was a lovely place to be inside and you could drive it fast or slow and even track it and it wasnt rough at all.
