Tuning pierburg......

[isolove]

Hi.
In the end of 2022 I make new, my Punto gt2, engine.
I have on the car the chip seb2,exhaust 60mm,and camshift from gt2.
I close the valve and I use the car as stock......
I find the pierburg an I try to make it work.
I follow the pick (attach).
Result:
I don't have overbost,I don't see more from 0,8bar
But the car looks going way better!!!!
Whats goin on?????
I have to put back the stock chip???

I think that you cant increase the boost pressure with the pierburg valve. You need a manual boost controler.
