Thanks.
I did have a look, just not a lot of internet where I am right now.
Ideally the top end would be lower AFR. Maybe tuning it won't give any more - you may be at the limit. In which case dropping WP will only make your mid range worse, and ideally it would/should be smidgeon higher.
How often do you plan at running at 6000 rpm? I would def not run any more boost tho and as I think spuggy? noted - he has run like that for some time. Your only other option is to try dropping WP by about 0.3-0.5 bar to get the 6000 rpm AFR down to safer limit, and put up with the lower AFR in the 4500-6000 range (assuming you fit a leask sw to deal with the rpm below 4500)
