09 z06 7.0L popped a p0601 , quick question please ?

Hello , quick history on this vehicle I own ,back in 2016 did cam, head work, ect?, in my shop. tuned with HP ,put a few thousand miles on it ,just recently was idling and stalled and wouldn't crank over until I cleared code. scanned found p0601 in engine side of the shop scanner , so with that being said after going through diagnosing electrical system ,I do believe I have to replace pcm due to having some sort of internal failure. Now my question is after my local dealer flashes stock tune in new pcm ,can I just download my tune into it or do I have to purchase credits? I have read many forum threads here but I need correct direction or procedure. ty in advance. Fred W.

A new computer would require credits.

From there it would be wise to do a copy/paste only with your old tune into this new computer. That will take all over 30 seconds to copy over all the data to make it the same.
