From your post, I assume that you want to open the chokes a little and try it. You can then go further if need be and not open it too much since you cannot reverse it. If you do it yourself you have some control and don't have to send it across the country several times but if you don't have machinist experience there is a good chance you could wind up with a basket case with each barrel shooting in a different direction.
Why don't you call Mike Orlen and see if he has advice as to how to proceed.
It is a wise approach to opening chokes. Good luck with it and do report back to let us know how you decide to handle it. We might learn a lot from that.
Best,
