septune not holding air

[pwrtrainer]

LBS overhauled the shock and it wont hold air, replaced the schrader valve, and again it is saggin way too much, 200 psi, now at 150. should i just PUSH it?

Take it back, show them the receipt for the work done, and have it fixed properly.
Did they put the shock in H2O and see where the thing is leaking? Should take no more than 20 mins to have this thing repaired (if it is a seal/valve problem and that they have the parts) and you'll back on the trail in no time!
Regarding PUSH - wicked aftermarket upgrade for your shock - your choice
