10.20 bar= 148psi ish across all cylinders.
Car was stood for a while. Since has had full oil and filter change.
Also being driven a bit more now.
Car has about 36,000 miles from new.

More or less a standard car with boost controller, remote oil filter, top mount intercooler, std air filter, std cat, uprated exhaust back box.

Okay?

If this is standard maybe someone knows what the reading should be but the fact it’s even on all clyinders can only be a positive thing surly

A1 readings for standard healthy compression .
closer they matched the better .
. Good quick and dirty way get a basic idea if a built motor been done well is by compression balance .
They always pretty close when healthy and nissan factory built .
