Your both partially right and wrong.
That stock dash gauge on the ng900/og9-3 is computer controlled and can be set to show whatever range you want by a Tech II. So you could have all the way to the end of the red as 5psi if you really wanted to.
However if both dash gauge settings were not changed then yes this could be relevant in comparison regardless of the T5 vs. T7 and show something isn't right with this viggen which is pretty obvious.
Check the plugs, MAF, DI, BPC, vacuum lines, and the wastegate actuator as well as were the base boost is set.
