This guide is for people with aftermarket/custom hardpipes. For those of you who are running the stock plastic pipes, read this to get an idea of what you will be doing, and then refer to "Mach 3.5 Turbo's" thread for attatching the HKS to the stock pipes, found here:

If you have specific questions about the installation process, ask them here. Please put ALL other compressor surge related posts in my other thread: http://www.msprotege.com/vbb230/showthread.php?s=&threadid=39676, or in sonicraze's thread in FI: http://www.msprotege.com/vbb230/showthread.php?s=&threadid=39433. Or you can PM me.
I would like to keep this thread organized and informative. It will make it better for someone who needs help with the install.
The iON FMIC/hardpipes, and HKS SSQV are what were used on the car in the pics.
1. Assuming that you are running the stock by-pass valve (BPV), and hardpipes, choose an aftermarket BOV that you like. The HKS SSQV, and the Greddy type-S work for sure. You will also need a stainless steel or aluminum flange that is compatible with your new BOV.
2. Remove the section of hardpipe that connects to the throttle body(TB).
3. On this section of pipe, you will want to make a hole that is the exact same size as the inner diameter(ID) of your flange. Make this hole no closer than 3", and no further than 14" from the TB.
4. Have your flange welded(or weld it yourself) so it lines up with the hole that you made on the hardpipe. This cost me less than 25$ to have done at my local welder.
5. Attach your BOV to the now welded flange/hardpipe, and reinstall into it's original position.
6. Run a dedicated vacuum line to your new BOV, or tee into a vacuum line close to the manifold, and run as short of a line as possible to the nipple on the BOV.
7. This is the key: Leave your stock BPV in place.
8. You will now need to adjust your valve. Go on a drive and take a wrench for adjusting. The adjustment bolt on the SSQV is a 10mm. Start with the bolt at the loosest setting it can be without falling out, and tighten it 1 full turn for the initiall setting BEFORE you drive it. Test it and if it sounds like the valve is opening just a little too early, tighten some more. Repeat this process untill it performs and sounds the way you want. You want the valve loose enough to fully open under boost, but not so loose that it opens too early.
You're done! Now go and drive your gobbleless car! You can now scare innocent bystander's with a different sound
Enjoy
If you are running hardpipes and an aftermarket BOV and are still getting the surge, the steps are simple:
1. Reinstall your stock BPV to compliment the aftermarket BOV you are running.
2. Give your BOV a clean vacuum source.
