I replaced the turbocharger and adjusted it with ktuner v1.2,
At present, the boost value can only reach 26.5psi, but I set it to 29, sometimes even 30, but the boost target will never exceed 26.5PSI

My tune: 26.5psi is works
Honda Civic 10th gen Cannot use more than 26PSI boost 26.5

Honda Civic 10th gen Cannot use more than 26PSI boost 26.52


But 28psi not works
Honda Civic 10th gen Cannot use more than 26PSI boost 28.5

Honda Civic 10th gen Cannot use more than 26PSI boost 28.52


What limits my boost?
28.5 tune not works this is my tune and datalog .

Unless you plan on blowing your engine, 29-30 psi is too much for the 1.5T...

With the stock rods, I wouldn't go past 25-26ish but even that is pushing it if done on a regular basis IMO.

I replaced the enhanced engine, which is enough to support 29-30psi, but my target value does not match my set value, who has any comments?

I shouldn't need a disclaimer for this, but don't do it if you don't have the supporting setup and know what you're doing with the info.

In the example where your final boost target table has columns for 26 PSI, increase the final output in the table itself from 26 to the value you want.
