The turbo outlet pre intercooler is a false reading - pressure drop through the IC isnt measured.

Want to make the engine perform at its best - pick up the wastegate modulator from the inlet manifold (post IC) as well, gives a real boost reading to the wastegate.

Where I teed mine in, near the wastegate modulator, it reads the exact same boost as the Nanocom as well. Would there be much of a difference putting it where you said Tombie? As in the PSI reading on the gauge. So would I be seeing say 1 or 2 PSI less then what the real reading is because of where I have it?

What happens if something gets blocked up? Eg. Hose issue. Won't the turbo over boost while the gauge reads low? I figured measuring close to the turbo is safer, although it doesn't match what the engine sees. However being no expert I've really just made a lot of assumptions.

Thanks all for your advice I have taken it to mtq turbos they said plumb it into modulator pick up line .
