Too much specified boost
« on: February 29, 2016, 03:44:49 AM »
Hello, i got polo gti 1.4 tsi dsg. Vcds shows 2600, 2700mbar specified boost. Car has got only intercooler and exhaust system. Sw is standart. I changed first map sensor before throttle. But nothing changed. What could be fault? Thanks.

Exhaust is now more free flowing, so amount of boost generated for a given duty is more, so you get an overboost?

I dont think cause of exhaust. Standart cars like a maximum 2100hpa around specified boost. Also car doesnt give any fault code.

Put stock hardware on and see if it does the same then.

So you post a noob question in the data logging board, without a data log?

You really need to post logs, also is it the twin charged engine?
