When I raised the nose of my stock forks by adding air, it eliminated most of the dive of the stock front end and definitely increased cornering angles..
More air, less dive.. The air acts as progressive springs (with the stock springs).
Post #24 shows # sag/ dive

Love the mod, super easy, nose isn't lowered any like the R6 forks which would exasperate the issue.
Its been over a year, no oil leakage, added 2-3 PSI in the years time.
I have risers so you would have to make sure you can access the schrader valves.
Just my 2cts..

Much more than 15 PSI, the ride is a little too stiff for me. At 15 PSI(each leg), less than half the sag.
