Hello,
Long story short I had my actuator replaced with a 12psi spring and ever since replacing I had a overboost issue. The person who fitted the upgraded actuator said he fitted it so the wastegate is closed nice. We lowered the duty cycle to about 10-15% and still overboost. I changed the MAF from a 2bar to a 3bar map sensor
I've shown a video and pic of where it overboost and cuts. Can someone advise me anything as the actual boost hit 3000mbar lol
My mapper said it has to be actuator that's wrong adjusted.
Also you can hear turbo spool with only like 10-20% throttle
