Hello,

 

I have a 2017 Fabia III with the 90hp 1.2 TSI engine.

 

I thought that recently it feels a bit down on power and wanted to see if I could extract any figures with a Bluetooth OBD dongle and a scanner app.

 

Using an Android app called "Car Scanner" and doing hard pulls in 2nd gear with the engine warmed up, I got a "Calculated Boost" figure peaking at just over 8 psi and a "Manifold Absolute Pressure" reading peaking at just under 23 psi.

 

Can anyone tell me if these figures make sense please?

 

Thanks.

Just proves that atmospheric pressure really is round about 14.5psi.

 

Sorry I've checked what the expected boost range is.
