I have around 105 on my 99' ox66 200HP 3.1L EFI, and it runs idles and performs flawlessly. As mentioned each gauge reads differently, within 10% is the important thing. If you think you have an issue, you can always wet and dry test. Wet testing mine (teaspoon of oil in the cylinder) has about 108PSI, so I'm not concerned about a ring issue, or anything of that sorts. These motors are amazing, keep clean non eth fuel in them, ring free/seafoam/whatever you prefer, clean the O2 and drive them.
