If your shock is in need of service and/or you are not satisfied with it's action, then definately getting it Push'd is worthwhile. Their service is quite excellent, I've had 3 shocks done by them and all have come back very responsive & plush, eliminating the harsh bottoming I've found my DHX's to have. If this is a new shock and bike I'd say ride it and dial it in and down the road when it needs service send it in.
