Why is my Cummins ISX not getting turbo boost?
I have a cummins isx that has a loss of power and not getting any turbo boost pressure. I have checked all hoses, air cooler, and dont find anything wrong. I am not getting any active codes either.

Is it possible to lower the boost ratio?
It is fairly easy to change the boost to get the best combination of performance and power, but it is extremely difficult to change the compression ratio, especially if you want to lower it. Additionally, you will make more total power with a low compression, high boost engine than you will with a high compression, low boost engine.
Why does my ISX low boost have soot in it?
The soot can build up in the moving parts and the actuator can’t move it properly. In the 2nd video, you can see the turbine housing. The vanes on the turbine wheel fit in the slots of the rotating collar in the turbine housing at the left. If those slots fill with soot, the that collar can stick as well.
What should the compression ratio be for a boost engine?
Table 1 shows that you obviously can’t try to run 10 pounds of boost on a 9.0:1 compression ratio engine. This gives you an effective compression ratio of 15.1:1, way beyond our 12:1 figure. If you are building your engine from scratch, it is a good idea to try to build it with a relatively low compression ratio, such as 7.5 or 8.0:1.
What should I do if I don’t have Cummins program?
A quick check if you do not have Cummins program is to remove the actuator and apply air to it.At least 60 psi of air is needed and the actuator should not leak any air and move 12mm with out any binding or sticking. if not it will need to be replaced.
