Avalon Calibur hopup

I’ve recently purchased the above and was wondering what hopup I should get to upgrade the standard one with? I’ve upgraded the spring to a SP110. The next thing is the hopup and need some advice.

Hi and welcome. What is wrong with it? Why do you feel the need to upgrade a brand new gun?
