How are you sending your suspension out to the tuner? Why not send them out in a gun case and have them returned in the same case? I personally would never trust my suspension across the country in a cardboard box. Too bad you had a bad experience with not only shipping but the valving as well. Looks like you will have to send them back and forth a few times to get it right.
It's one of the reasons I use local tuners or tuners that actually ride the same stuff I do
