You could change the string guage... That would result in different tension.

Yup, what he said ^
also you may want to raise the action a bit as wel

I've changed string gauge. Tried xl all the way up. I will try adjusting the action though. Thanks

Raise the action, move the bridge saddles back to properly intonate, adjust your truss rod to taste and you should be good.
