The WW will fix it most of the time but to never hear it again you'll need the ATS.

If taking your foot out of it and running 45 mph on the interstate is the fix, I need to spend some more money. I am unable to utilize 6th gear at all while pulling the 5ver due to "surge". With the stock air box I neither hear, see or feel the "surge". The filter was the only change since last hard pull. Why have all that extra power and be unable to use it?

Sometimes the pressure release is more pronounced when I have my foot deep and let off just as it's shifting into second or third...pretty sure that's normal though...it'd better be because I'd hate to give up that sound!
jsmahan, you should try a wicked wheel. It will fix the surge most of the time. And if you don't think it's good enough you can always run it along with your ATS compressor shroud. A Wicked wheel is a lot cheaper then a new turbo.

I had planned on the WW but at some point here I read you actually lose boost with the WW and that the stock wheel may perform better than the WW with the ATS. Just trying to eliminate the "buy this to fix problem caused by buying this". At some point things (mods) should stop causing other issues. It seems the more we throw at these things the more they need.

Now, I know you can't hear it surge the stock airbox, and I can't even feel it with the 6637 installed, but how are you seeing it? Did the needle on the boost guage bounce when it was surging, with the 6637 installed? And, I assume that the needle no longer bounces with the stock air box? I'm just trying to see if the more restrictive airbox is really causing the surge to actually stop, or just that you can't hear it.

Yes you can see the needle on the boost gauge bouncing in relation to the surge. Actually starts just before you hear it. With the stock box, no surge seen, heard or felt. I can feel it due to loss of power. I know isurge can cause damage to the turbo but it just seems weird that there are no signs or symptoms w/ the stock box

So, what amount of weight are we talking before you will get the turbo to stall(stock)? If the WW is installed will that prevent this compressor stall(up to what amount of weight can be towed before the WW will stall?)
