A boost controller can be a simple manual control which can be easily turbocharged car, or an aftermarket electronic boost controller. Found some better USER instructions.

It is not used in this installation. Disassemble the center divider. There are four screws in the center storage compartment; remove these and the compartment should lift off. Set it aside. Now remove your shifter knob and shift boot. The knob unscrews and the boot may be removed by gently pushing forward on the bottom edge; there are four clips which hold it in, two top and two bottom.
Set these aside. Next look along both sides of the divider; you will notice four plastic screw caps. Pry these off with the small flat screwdriver and remove the screws underneath. The center divider should now lift off easily, set it aside.
Disassemble the lower dash panel. There are four screws, roughly one at each corner which hold it on. Remove the screws and slide the panel downwards and towards you and it should come right off. Remove the metal plate beneath the steering column. There are 3 bolts and two nuts which hold it on. Use the 10mm socket and the plate will come right off.
At this point you should be able to see the ignition harness. Take the wire harness that came with the Blitz kit and tap the RED wire into ignition power; I have a Blitz Dual Turbo Timer and tapped the power line from that instead. You could also tap stereo wiring, I suppose. Run the harness along the left side of the center divider. You may find it helpful to unclip the exisiting bundle of wires and clip the Blitz wires inbetween the divider wall and the existing bundle.
You can unclip the existing bundle by squeezing the grey plastic clips with pliers and sliding them out. Run the harness into the engine compartment. Peel back the firewall carpeting behind the drivers seat and you will see a rubber grommet which wires run through.
Take the end of the Blitz wires and slide it through the slit and into the engine compartment. Slide it in about 1. Tidy things up with the wire and tuck it under the appropriate carpeting. Mount the unit. Depends on where you want it. I put mine in the left center air vent along with my TT.
It required a bit of cutting but nothing major, just the pull-out plastic vent. Another popular spot is below the fog light switch; my TT was originally located there.
Running the Vacuum Hose If you already have a vacuum line running up to the dash, tap your existing line to connect to the Blitz unit and skip this section. Run the vacuum hose. Take the 14 feet of 4mm hosing and run it along the center divider similar to the Blitz wire harness.
Cut a slit in the grommet and stick one end of the hose through. Install the vacuum T. On the right side of the rear engine compartment wall you will see a small sensor with a hose running into it. This is the stock boost sensor. Unplug the hose going into the stock sensor and cut it halfway between the white filter and the sensor end of the hose.
Connect the hose. Run the hose from the grommet around the left and then rear edges of the engine compartment to your newly installed T. Use zip ties to secure the hose, but be careful not to pinch or kind the hose.
Valve Unit Installation 1. Install the "OUT" hose. Cut two feet of the 6mm Purosil hosing. Take a look at the left side of the turbo. Slide the hose off the fitting and stick the now loose end someplace where you can grab it again easily.
Install the "IN" hose. Slide a hose clamp down one end of the remaining 2 feet of 6mm hosing. Next take one of the 6mm hose barbs from the Blitz kit and secure it to the hose.
Now find the hose you disconnected from the turbo and attach it to the other end of the hose barb. Use the stock spring clamp to secure it to the barb. Slide hose clamps over the ends of your IN and OUT hoses and connect them to the appropriate fittings on the valve unit. Here is how to disable the VSV. Locate the VSV. Slide under the car and look up at the engine. In the mid-rear you will see a canister shaped object and next to it an electric valve with two hoses coming off it.
This is the VSV. The hose of interest is the "U" shaped hose. Plug the VSV. Disconnect the "U" shaped hose from the VSV unit. Slide the hose clamp further down the hose, as far down to the bend as possible. Note: I did all of this without jacking the car up and with one hand. Depending on the diameter of your skull you may have to elevate the car on ramps or jack stands to get enough room to work.
Gain controls the overall boost response by constantly modifiying the pressure coming from the actuator into the wastegate. Ratio controls the boost curve by adjusting how quickly and when the wastegate is allowed to open.
Ratio also affects your maximum boost. The unit will beep and you will see "M" flash on the display. The default gain is 5. Set the value by turning the volume knob. You can adjust the value anywhere from 0 to Be very careful with gain, as setting it too high could cause overboosts leading to engine damage and possibly detonation.
I spoke with Blitz and the gain setting is intended to compensate for the varying spring stiffnesses of external wastegates. The recommended setting for the SW20 is 0. This allows you to switch boost curves "on the fly", somewhat useful, in the sense of city and highway modes. To set a ratio, first select a channel by turning the mode knob until you see either 1, 2, 3, or 4 on the display. The channel number will begin to blink and you are in Ratio Set mode.
Press the volume button until the words "boost" or "peak" do not appear. A number will appear in the main display area; by default all channels are set to 0. Turn the volume button to adjust the value. The value can be anywhere between 0 and According to Blitz, the Ratio is the percentage of boost which will be utilized.
This in turn will affect your maximum boost; I was told that with a setting of 25, boost should max out around 0. The word "WARN" will be blinking on the display. Here is where you set the warning value. Turn the volume knob to select a warning pressure; anywhere from 0 off to 2. Press the volume knob once now to set the warning ratio.
The warning ratio is the amount of power reduction that will occur when the warning value is exceeded. Note: The value you set here is NOT a boost limiter! It is quite easily possible to exceed the set value and by large amounts depending on your ratio setting. The DSBC will regulate boost to below the warning value and will prevent boost spikes. It works in conjuction with the warning preset.
Turn the mode button until you see "L" blinking on the display. In the main display area you will see "P 0". Turn the volume knob to adjust the scramble power; this is power in ADDITION to the ratio setting of whichever channel you are in; so if you are in channel 1, set to 25, and set scramble power to 10, your scramble mode boost power will be Also note that you can set negative scramble power also.
Press the volume knob and you should see "C 0". The value you set here is the time in seconds that your scramble power will be applied once you hit warning mode.
