I ran the pistons in the same set-up as JohnM posted.

I ran a the piston set-up back to back with my existing shocks in practice at the RHR national.
Same oil, same holes just Ghea vs Standard.
The difference was noticable, mainly down the straight. The GHEA pistons 'return' faster than standard ones making the car 'float' over the bumps a bit better.
The jumps at RHR weren't so severe and in your face so there was no noticeable difference there. Both pistons had time to work there way back to full droop.
