I recently started my Med board last week (Friday). But I have a sleep test I'm waiting to schedule and I need an MRI on my shoulder is it too late to get it in my records before my NARSUM? How do I stall? Any advice??

Welcome to the PEB Forum!
After assignment of a PEBLO to develop the MEB case file for MEB phase of the IDES, the PEBLO will complete Part I of VA Claim Form 21-0819, VA/DoD Joint Disability Evaluation Board Claim, which lists the potentially military unfitting medical conditions. Your PEBLO will counsel you on the process and identify others who can help. You will then be referred to a DoVA representative known as a Military Service Coordinator (MSC).
The MSC will counsel you on the DoVA portion of the IDES process and help you to complete your claim for consideration of medical conditions (other than those referred by the military physician) that may have been incurred or aggravated during service (VA Form 21-0819, Parts II-IV). The MSC PEBLO will request all necessary specialty and physical examinations.
A combination of military, VA or civilian medical providers will perform the examinations. The tests and results will be summarized in a Narrative Summary (NARSUM). The DoD MTF is responsible to produce the NARSUM. Your PEBLO will make sure all the necessary information is added to your IDES case file; therefore, it's vital to have copies of your sleep apnea study results and MRI final report if available.
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer."
Best Wishes!
My MRI will either show I have a bad shoulder or a pinched nerve in my neck. The sleep study I guess will only count for VA right?
If none of the conditions impact duty performance (either individually, or collectively) then they will all only matter for VA purposes. I would not necessarily cede the point that the conditions don't impact (at least collectively) your duty performance and are, therefore, unfitting. (However, rest assured that the PEB won't rate them unless there is evidence that there is significant functional limitation due to each condition; I think this limited standard that they apply is legal error, but that is what they will do). All service connected disabilities should be rated by the VA.
Will an MRI and sleep study not be enough evidence? I mean how in dept does the evidence need to be if a Dr. diagnoses a pinched nerve after only being seen twice is that not sufficien
I think you are missing the distinction between diagnosis of a disability and impact on duty performance sufficient to warrant an unfit finding. Take a look at the regulations and posts on this forum on fitness....the distinctions are important.
