    Post VGT position jumping

    Is my VGT position supposed to be jumping like this at idle? I have a stainless diesel turbo with DRD tuning. I just hope it’s not the actuator since the turbo is only a year old. https://youtube.com/shorts/jX_FHsSRs...35R9K_jXUWb5nq

    What's actual vs desired showing other than the % value you are watching?

    I’ll have to check that. So if the desired is the same as actual it should be fine but if the desired is different then the actual there could be a problem?

    In your video you are monitoring the actual VGT %. Monitor both actual and desired together, they should match and follow closely. Plotting them on a graph is the most accurate way to compare them. Ignore small momentary fluctuations.
