Less than 2 week turn around from when I shipped it to when I received it back. Was planning on a month or more. I shipped mine for peace of mind with subtle moments of twitching but otherwise functioning and no codes or drivability issues. Now Upon his inspection it was determined a capacitor was required so he replaced, packaged it very delicately. Upon install and initial run up, the subtle twitching was completely gone. I am very pleased and now I'm looking at sending him a pcm/psom combo to give me peace of mind on another truck. High quality personalized service and shares the same passion of making these trucks reliable daily drivers ad do I. Definitely recommend even if things appear working, it'll be worth the peace of mind. Thank you again.
