I put a Wicked/Whistlin' Wheel and a Turbomaster on my turbo (and also rebuilt the guts with a kit from Guzzy at the same time). The WW provides lower power, is much louder (and I just have the 6637 air filter), but seems to spool quicker and does not surge. The Turbomaster allowed me to adjust the performance back up to the stock wheel and it holds boost right where I want it much better than the stock blow-off valve. So, it was a good mod overall for me to eliminate the surge in my truck. However, I'm sure there are other/better ways to go about it.
