Unless you are getting surge, no. The WW does flow less air and does whistle a lot louder...like a 6.0. I could hit about 29psi with my stock wheel and I can hit about 21psi with the WW. But I did not see any performance loss and I have no more surge. I think I should be building more than 21 psi but I think I may have screwed my waste gate solenoid up when I took the housing off.Itll perform better though, right?
Could a BOV help with that instead of replacing the wheel? Has anyone ever put one on their truck?You'll be able to see surge in your boost gauge fluttering too, and boost will quit climbing. My truck used to surge horribly when I got on it and started accelerating in my 140 hp tune. Sounds cool, but not good for the turbo.
