help turbo Pressure stok audi a3 2.0 tdi 140 BMM

[alessio105]

hello guys I present my alleged problem...
I have a audi a3 2.0 tdi 140cv engine bmm with the original map but with the dpf deleted ... doing an in-depth diagnosis known a strangeness in the pressure of the turbo..so if for example I put myself on the road in fourth gear, and thrust the gas from 1500 rpm up to 4000, the pressure of the turbo at around 2200 rpm reaches 2370 mbar and up to here everything ok, but then from 3000 to 3200 rpm about salt from 2370 up also 2470mbar then re get off to 2370 up to 4000 rpm...while comparing with the value, the goal should always remain constant in 2370 as from the map ..now I ask all of you and normal to 3000 rpm, has that peak so high compared with the goal?? someone that has the same engine I can say if your behaves like this? I should point out that the turbine is new so I have no problems with the clamping system of variable geometry...thanks to all in advance

from 2370 to 2470 let's talk about an imperceptible 0.1 bar of pressure. Given that you have removed the dpf we can stay well this variation may depend more on the geometry from the values read from the flow meter because the drain empties with much more freedom..

considering that this is a very fair response
