Trying to figure out what this fluttering noise I get from 2000 rpm to 2700 rpm and about 1/4 to 1/2 throttle. It's a fluttering sound that I thought was an exhaust leak but after pressurizing the exhaust and spraying all the v bands with windex I couldn't find any leaks. Has anyone hear a similar sound or have any suggestions of what to try out. Hoping to get it squared away before the car gets tuned in a couple of weeks.
