Yeah I did them all together, wasn't too bad at all. I double checked everything and it's all properly installed, these are the following codes from JB4:
121533 boost pressure sensor, plausibility: Pressure upstream from throttle at motor stand
118002 Mixture ECU: mixture too rich
118001 Mixture ECU: mixture too lean
1F140A No Description Found
Edit: sorry also updated the firmware, didn't help
