I would advise to put it in the intake manifold because that's where we want to know how high the pressure is. We can make the assumption that it's a bout 2-4 psi higher at the compressor outlet (with or without an IC), and we know that running 20 psi at the inlet manifold is safe because people have been doing it for about 10 years on these cars.
Stock boost is 14 psi, when you stage 1, the extra fuel flow takes it up to 16 psi without any adjustment, from that point on you will need a boost controller to get a bit more boost.
Ruan is right about the long boost controller pipes, it does make it spike a bit, but then it's easier to adjust if it's at the top of the engine bay. Try to minimise the length of the pipes as much as you can.
Once you fit an intercooler it will likely drop back to about 14 if you have a stage 1 and a big intercooler.
