Using the conversion formula from S4Wiki, load value 180 would result to approx. 1.1 Bar? Or maybe I'm just bad at math haha. I know it's not a direct relation to "boost", but it makes it easier to grasp the idea.
Conversion from load->boost vary between engine sizes, factory calibration philosophy etc.
In your car 180 load is around 1,2 bar not 1,1
Stock turbo is capable to do 180 load and maybe slightly above up to around 5000rpm in ideal conditions (cold weather) and with supporting mods like exhaust and IC. Then it will fall off regardless.
Simply speaking stock load axis is enough for stock turbo to make max power.
Of course 180 load may not be sufficient if you tune for diesel-like power curve with insane low-mid-range torque falling hard afterwards
Some people like to have car that fells/looks fast but is not
If you want to have faster car - put bigger turbo. Stock TD04HL-16T is week as fu**
And do not put any stupid 19T or 21T or whatever hybrid. All those TD04 family turbos do is clog the exhaust
Any fun starts from TD05 or GT30 etc
2.3 engine bears 1,4-1,5bar. With proper turbo this gives 4xx+ HP and this is more or less when fun starts
Of course then you have to recalibrate MIOP/MIRL tables
