I installed an ecu yesterday at my local dealer, but ever after hours of driving I have not seen any increase in performance ?!! The boost only reaches 0.8, is there anything wrong or do I have to get it reinstalled ?

 

Hi...what kind of ecu upgrade did they install?
Giac or Evoms?
I have a GIAC ecu upgrade which comes along with a little device"flash loader"to plug into port in order to go back and forth between stock and tuned
Perhaps you are in 'stock' mode
My max boost is up to 1.1 bar..and it builds up faster with much less lag...

 

None of the above,
It was speedart's a gift from a friend. Its a piggback system, so I don't exactly know what to expect.
