Compression ?

Anyone know what the compression should be for the 3.4 ltr petrol engines.

Mine are:
1 - 210psi
2 - 205psi
3 - 210psi
4 - 210psi
5 - 210psi
6 - 205psi

Engine feels sluggish. Only traveled 112,000k/m and I'm having gas installed in 3 weeks.

Don't know what I'm looking at Mike ops: but my Gregory's says...

Compression pressure at 250 rpm
(minimum)
Nominal................... 1200 kPa
Minimum.................. 1000 kPa
Allowable variation.... 100 kPa

Hope that helps.
