Falcon may be good but wow their info on them SUCKS! Give me a straight answer on what each adjust does already.... @TeraFlex Suspensions @TeraFlex
This is a guess since I can't find any info in their docs but it looks like the adjust knob on the piggy back is their compression adjuster?? big lever knob would be low speed compression and the little inner knob high speed compression? (that is what is standard in every piggy back dirt bike shock and really all you can control at that location, rebound happens at the piston)
The 3.3 also have a quirky turn the shock shaft 360 degrees thingy which seems to be a half baked way to giving some adjustability to rebound.

Based on what you say sounds like you don't have enough rebound dampening. Start there. Un bolt the eye of the shocks and turn them 360 degrees to engage " performance mode" aka more rebound damping and set your compression adjuster knobs in the middle of their adjustment range.
Go for a drive. Did any thing change?
Those high heaves you are hitting trigger the high speed compression circuit (aka high speed is not related to vehicle travel speed, it is how fast the shock compresses on an impact) square edge hits in a road at speed will cause a high speed compression action. By adjusting the high speed circuit of the shock to harder you are basically adding more resistant/damping to the upward stroke and slowing down that upward movement.
If the adjusting of the rebound (360 degree turn) doesn't help start playing with just the high speed compression adjustment. Turn it one click harder (CW) from your middle adjustment go for a drive, did it help? if not turn it back to middle (aka base setting) and then turn it one click toward soft (CCW). did that help? If a little go one more click toward soft (CCW) and see what that does, keep repeating this, going back to base setting and then adding 1 more hard or soft click. Work through the full range until you can develop a feel for what each adjustment direction does and how it feels. You will start to get a feel for which direction to go in the adjustment based on how the truck feels.
My guess is you need more rebound and a touch more High speed compression to dampen the upward stroke on those square edge hits.
