okay im about ready to finally start my engine for the first time and i have just a couple questions...i have removed all emissions stuff, i am down to 5 vacuum lines...

- wastegate
- BOV
- map sensor
- FPR
- boost gauge

which of these lines can i "T" into each other? where would be the best place to run these lines to? ive read a lot about this but am finding mixed opinions. im running s5 manfolds, here is a pic of my set up so far. any help or pics would be greatly appreciated, thanks!

You definately do not want to tee off FPR, pressure sensor, or bov. Boost gauge does not matter so much but I like to get dedicated vac/boost sources if possible. WG is not so much a big deal either if you tap the compressor housing and it's ok to tee of it since it's a necessity for boost controllers.

You should try to minimize the numbers of tees. The wastegate should be connected to the compressor housing outlet; there's usually a blank spot just for that purpose. The FPR should be connected to the angled nipple on the inside of the LIM. For MAP sensor use either the top nipple on the front of the UIM or the bottom nipple on the rear of the UIM. For the BOV and boost gauge you can use whichever one you didn't use above and the one on the right side of the UIM just behind the BAC valve.

You don't mention the fuel injector air bleeds. You should hook those up too, as they improve fuel atomisation. They connect to the top two nipples on the rear of the UIM. The primary air bleed is the nipple in between the oil injectors on the LIM. The secondary air bleed connects to the rear side of the rear secondary injector boss and continues from the front side of that injector boss to the rear side of the front secondary injector boss.

You should get rid of that awful intake too. Get a filter with a neck that matches the turbo intake. It's a shame you've made the turbo-to-intercooler pipe like that, as it looks like it would be difficult to properly separate the intake from the engine bay. At the moment you'll be sucking in very hot air straight off the radiator...
