I got the 710N installed and now its making a low hollow air blowing sound at 2700 RPM (like blowing air over a bottle at the right angle)

Is this just the break in phase and will go away or should i be making an adjustment to something??

Any input is appreciated

 

If it is sort of a faint "honking" kind of noise that usually means the DV is bad. Im sure thats not the case if yours is new though.. Double check the connections and elsewhere for leaks.
Could also be a kink in the vac line that goes out the top of it, that can easily happen if its seated the wrong way.
