The tightness is achieved partly by the bungee pulling the cylinder round and inwards, counter to the boltsnap fastening on your hip D-ring. So move the hip fastening round on the cylinder a bit to adjust the valve position at the other end.

Length of leash can also be a factor, most people run the leash up towards the tank. I find the opposite works better running them downwards towards the bottom, especially when using Ally's.
Why not get a session in with a proper sidemount instructor - he / she can personalise your whole set up.
