I recently had some work done tuning my 429 with a Demon Carb. It's in a Shell Valley kit. It seems like it's starving for air when sitting at idle. With the hood closed the idle goes down by about 150 RPM, when I open it up the RPM goes back up. When I'm driving it runs great as long as it's moving. Even the idle is good as long as it is moving. Any thoughts on what could be done to fix this or shouldn't I worry about it.
