Talked to a few and they say "yea we fix problem A (B or C), no worries" but haven't gotten somebody to say "we fix everything, and test it with a test truck to make sure it's 100% before it gets to you."
i had the pcm repaired on my 98 years ago by a company in florida, they charged 150. they tested and repaired it and told me what circuit the issue was on.
