It's almost definitely not fine. What you should do is hook up a vacuum gauge to your intake manifold and have someone idle the engine up a little and watch the vacuum gauge and see if the vacuum goes up or not. Or if you have a scanner that will show manifold reading you can watch that as you idle the engine up. What you want is the highest manifold vacuum at idle and that's where you set your idle at. Mine was at 500 rpm when I was stock but after the cam swap the tuner set my rpm to 7-800 rpm.
