In your particular case, or as a general rule? Seems kinda of silly to offer an "upgrade" that doesn't work...

Bryan forgot to do the adjustable rod on mine (it is supposed to be part of a Stage1 so I didnt pay extra for it) and I asked him how he made the mod. He told me "I cut the rod, weld a coupling nut on it. Then thread the rod end and adjust it that way. Only around a 2-3 additional psi is all you can get out of it"

So he may be doing it as a bonus so someone can get a couple extra psi over stock. I think it might be better to fit an adjustable helper spring mechanism that would better match to typical goals instead.

Our HKS EBC and the unaided WG actuator couldn't keep the WG closed so we had to add the helper spring.
