Here are a few threads that have lots of valuable info.
They helped me to decide what was best for me.

I spent about $550 installed for the gauges, pillar pod and dual stage boost controller.
I installed all myself except the EGT probe...For $25 a speed shop jacked the car up and drilled into the exhaust manifold - I have no jack or ramps (and my mechanic was too busy this week).
Hope this helps..
