If you are trying to control boost do this...........
FIRST: make sure the boost you want to run can be supported by your programming. NEVER do it with a stock porgram. I.E. call you chip programmer/distributor and verify the fuel richness factor, over compenstion for timing and air flow.
Once you have done this you can utilize a DIY boost controller or a manufactured one. You do this by circumventing the N75. If you have a DBW car it is not advisable to do this.........you will throw codes and potentially go into limp mode. DBW cars communicate back and forth with the N75. NDBW cars do not.
Now that you have heeded the warning proceed at your own detriment.
There are two vaccume hoses on your turbo, one from the external wastegate (the goldish cyclinder thingy at the upper right side of the intake impeller housing) and one from the back side of the intake impeller housing. Both of these lines connsect to the N75. Remove them from the N75 and bridge between them with your boost controller. Be sure to have the active side connected inline such that it releases on the side of the wastegate. Set it to the desired boost pressure and go...........
