I don't feel its worth tinkering with to up it anymore really.
Mine is in excellent condition but I had a little issue with it when I first got it secondhand, long story short, the anti tamper was removed and it was left shooting at 6.5 fpe. Got it sorted now and it's running at 11.4 fpe. I do like the cocking lever on the 510, it's similar to the HW100 which I think is superb. 10.6fpe is fine Mike, another 1fpe isn't going to make a marked difference, what calibre is yours ?
