(im not after the compression ratio of 12:1)

What are you getting? Don't forget engine hot and with full throttle.

CR @ 12:1 you say.
Let's call 1 bar=14.5psi for example (1 atm is a little greater), you can trim it later to specifics.
12 x 15psi = 174psi
If the engine is tired then reading way below the 174psi, but I'd be happy with a reading of 170psi (-10 psi tolerance).
