I recently jammed open the swirl flaps on my 2.4 Brera because of bad starting and poor tickover when cold. What a difference this has made to the car, brilliant. My question is this, now that the swirl flaps are permanently wedged open and the car runs well, is there any point in removing the flaps and replacing them with blanking plugs. Removing the manifold is a big job and not sure of the benefits of doing this when the flaps are I assume no longer a problem. Note the Egr is fitted with a partial blanking plate so the carbon in the manifold should be reduced. Your thoughts are welcome.
