Find out what his AFRs are on a stage 2 tune. Not talking trash just mentioning this out of real world experience. When GSR did a beta tune for me i had a lot of knock issues and upon closer inspection they were running me way too lean.
In full disclosure I've reached out to David Shoup too. Still waiting to complete communications with him.
