Chrony it first. It may not shoot so high.
Then your option is a spring shortening either by cutting the spring or shorthening whatever the spring rests on to give it tension.
How much to shorten it? Who knows. Do it a lil at a time and test till you hit your goal. Only downside it if its too short it may not activate the valve at all.
