Hey out of curiosity, anyone on here tested a healthy stock 4g63 starion motor? What compression do they have when healthy?

I think the figure varies from different compression testers but around 120psi for the stock starion with the 7.8 compression ratio.

120psi with accelerator closed, but ive heard up to 140 psi, probably with WOT while testing?

I've seen around 150-160 psi on a stock Cordia engine, never seen any difference between open and closed throttle so I never bother opening it anymore.
