They will T-into whatever boost reference source is available (probably charge pipe).

Have you ruled out adding a boost gauge/sending unit of some sort? I really like the idea of having a measure of boost at the intake manifold separate from any calculations or ecu interpretations so that I know exactly what the engine is seeing. I have mine tapped into the rear of the intake manifold, which was very simple. Just my

I haven't ruled it out. I was hoping the electronic gauges would work better. PLX does make a boost sensor module that I could hook up and use that value instead of a calculation. It just sucks because I have the original kiwi wifi and would need to get the newer one to hook up the sensor. I might just bite the bullet and do that though if I can't get an accurate reading from the calculation method. You're really never 100% sure with readings anyways. I had a boost gauge on my STi that was off by a couple psi too. My tuner called the gauge "optimistic".

My boost gauge is off by .2 psi.

There's a lot of guys selling gauges and stuff since they're changing their mind on boost. You might be able to vulture a gauge for cheap.
