I'm getting a significant boost spike and would like some help figuring out what might be causing it.
This is a log of group 11.
Vehicle is a converted auto, so it has an 11mm pump. Nozzles are DLC1019 set up by drivibiwire. I have pulled the VNT actuator off and cleaned it out, actually had little rocks stuck in it. It now moves smoothly. The VNT lever moves loose as a goose. There is no binding or sticking at all. All vacuum lines have been replaced.
The log is from 1500 rpm WOT to about 4000ish rpm.
What could be causing the boost to spike so high? What else can I check. Trying to get the boost spike under control so I can proceed with getting it tuned by Malone Tuning.
Thanks in advance for the help.
