If you have the adjustable Borla,isn't it basically a cutout already when using the wide open plate?Or actually no plate?

Maybe there would be a difference between the closed borla and an open cutout?

Get yourself a baseline run with it closed, and try to duplicate that run with the cutout open and see if you pick up any ET or mph.

What did you end up running? I bet you would have a better 60ft with it closed but a lower trap speed, but in the end I bet having it open would give you better results. I always just run mine open. Just experiment with it.

Maybe 1-2... 3-4 seems a bit excessive

I also say run a few passes with them closed and then a few open to see just how much you gain.
you will be faster with them open.
