well i turn the screw to the left it seems to act better until i readjust to get some rich readings,,,then caput it runs right back to lean,,,should i just keep turning the screw to the left or what,,,it becomes a real pain in the ass to retune the screw and keep getting out of my car..... so is there a easy way..the bov got louder and the pickup and launch gets better when i turn the screw to the left .should i get a voltage meter???
