how much should the vacuum guage read at idle. mine sits around -16 but i didn't think that was very good. i have put clamps on all hoses around the back of the supercharger and sprayed carb cleaner on all sc tubes to check for leaks and found none. there has to be another place to look i just dont know where it is. any ideas? -16 might be ok, i just didnt think that was low enough.
