Okay, I'm having a bit of a strange issue that is kind of hard to describe finally got it all in one good video for reference.
Remember that the truck is compounded, so turbo issues are not necessarily felt the same.
I'm having an issue where the boost reading in the mm3 will be substantially wrong but still has boost.
I finally put mechanical boost and exhaust pressure gauges in it to see what was happening.
You can see that when the boost is reading incorrectly, it seems as though the VGT may be trying to close to build growth, but when the boost is reading correctly, the vdt is open, and exhaust pressure drops significantly.
I put a new map sensor in it a couple of days ago, and I put a city diesel turbo actuator on the factory turbo yesterday.
The issue has been around for a while seems as though it potentially is getting worse, but it might just be that I can now see the exhaust pressure doubling.
This may be a Ray question,n but I figure I will ask to see if anybody else has dealt with it before I bug him.
