I caught the part about no chassis slap, I was just sayin'...
Honestly I haven't spent a whole lot of time messing with pistons. Our club has 4 tracks that we race at, each one is different, and I don't have the will to retune shocks for each one. I make small changes in roll center to suit the amount of traction there is and leave everything else alone.
But...if the wheels are coming off the ground when you hit a bump and the chassis remains somewhat stable, the shock oil is not providing enough resistance to that movement. The opposite is true if you hit a bump and the whole rig flops around. In that instance the shock oil is providing too much resistance.
Thicken the oil slightly and see if it improves. If it starts hurting performance in other areas of the track, stop, and back up a step.
