The recalibrated PT will show less than actual boost. You need to plumb a guage in - tee in just prior to the ECU port.

Minhea chip question.
The ECU now has a modified PT.
So when the car had the stock PT setting the dash showed 1.8 bar at "full"
Mine had leaks and issues which a few of us focused on and fixed/repaired.
Now the Chipped ECU only reads 1.6 max no matter what (it was 1.3-1.5 in the
Yes 93 octane fuel used........
Q: WHEN the PT is "recalibrated" does the dash display read lower because of
So 1.6 = 1.8/9 stock?
Also, where would the best place to T into the vacuum lines for a VDO boost
By the ECU not optimum?
I've been told chipped cars read 0.9 at start up, but my old 10V avant showed
0.9 non"chipped"..........even 0.1 under vacuum deceleration.
