Anyone know what the Boost and vacuum pressure values are???

Does anyone know the stock values for vacuum and boost pressure ? Have searched but can't find a thing for a 2013 A5..

Bought an app and it shows -12 psi on idle and up to 20psi of boost.. Car had a drop in AFE filter and turbo inlet hose !

Stock my 2014 a5 sits around -22 psi on idle, and ~max 14 boost. With my tune I see the boost peak above 25 on cold days.

What prog are you using to test groovy? I got those values from Dashcommander

-12 is the lowest vacuum and max 21 psi when I really stepped on the gas .. But I bought it with no tune!!

I've got a p3 boost gauge installed, I highly doubt you are pushing over 20 lbs of boost on a stock tune.

Took a pic using Dashcommander ... Everything else In the app seems to be accurate
