    Take it apart and check the spring and seals, clean off the grease and relube sparingly. Rebuild and check power again.

    Personally, I'd replace the breech seal and re chrono' it before she comes apart. If it's still low then maybe a full piston seal and guide tune up. You could even consider short stroking it. But you might just find the five quid seal fixes it.

    My money would go on the maxi kit from here. Best £43 you'll ever spend on a springer

    If the breech seal looks flat, replace it.
    If when stripped the piston seal looks brown and feels brittle in any way replace that too.

    Also be mindful of what pellets you're using.

    If you are getting 9.5 with pellets that are inefficient, this may well equate to well over 11 with a more efficient variety.

    Given its a HW80 and depending on budget a simple regrease with new seals may do exactly as you want it. Can't blame you for wanting more though!!

    It's strange, usually keeping the power down on the 80 is the problem

    When you do get to chrono it again use lighter pellets eg. RWS Hobby.

    Stick a ox spring in it but check power to keep yourself right https://www.gunspares.co.uk/products...-Airsporter-S/
