No, but you can force are in to a plenum (airbox) that makes it easier for the turbos to breath, especially if that becomes a restriction at higher boost levels.
Suck on a straw, then have somebody place an air nozzle on the end of that straw and try it again...
Wouldn't help you off the line, but could potentially provide gains at higher speeds.
More efficient air supply, less resistance on the turbos, less resistance on the turbos, less restriction on the exhaust gasses escaping....
All of this would obviously only be valid if...
1. there is a restriction
2. I knew what I was talking about
