you might get away with dropping your dwell a little, but you'd be best increasing the ROFD a little to compensate and avoid possible drop-off at speed.
try coming down 10 clicks and see how it cycles. if it's still good, come down again. once it stops cycling properly, come up one at a time until you get a full force cycle, check it will still do so at speed (if not keep coming up and checking) then add around 5 more pushes for summer, another 5 for winter.
should get you down a little. if you want more efficency get a lighter bolt, then go through the same process.
qev will make you even more efficient, but unless you're careful with the setup can lead to more breaks.
