Hello guys,
We are trying to tune the 1.4T 2019 Cruze but something weird is going on. I attached our last tune and log with a dyno graph. As you can see, from 4000rpm on the powerband drops to stock one. At the logs we can see that tb is closing and them opening again. No matter what we do, we cant past 220kpa of boost. Two tuners tried to do this cruze. I dunno if is something like protection is arming (if you pay attention to log, lambda target sometimes goes to .71 and them follow back).
I will appreciate any help.
Thanks
Rodrigo
