Stock boost is around 0.6 bar. I recalled back in the days when my turbo, ECU and injectors were still stock, I have raised the boost to 1.1 bar without an issue. I drove the car for 3 years before I upgraded all the hardware from Evo and dyno-tune the car to run at 1.6 bar.
The difference in terms of power was very obvious from 0.6 bar to 1.1 bar. Guarantee you'll grin ear to ear whenever you boost.
However you need to make sure your car is in very good condition. I was running the stock intercooler but with upgraded intercooler piping. The stock rubber pipes expands due heat and high boost loosing response. Good luck!
