How do I increase turbo boost pressure?
Once tuning on the dyno, we follow a simple procedure:
- Base run at wastegate pressure checking the boost level.

- Continue increasing the boost level in small increments and monitoring boost level and power increase.
What is low boost and high boost?
Posted August 11, 2010. Low boost is handy for wet greasy days – otherwise run high boost all the time. Running high boost doesn’t mean a thing unless you are boosting. That is, if you are cruising at say 80km/h in 5th then you are not boosting at all so it will make no difference what your boost setting is.
Can you run a turbo without a wastegate?
While in theory you could run a turbo system without a wastegate by carefully choosing a turbo that will only reach its maximum turbine speed and desired boost pressure at the engine’s max RPM, it’s really not practical in the real world.
What should I do if my cat C7 loses power?
It should bring up a code, loss of power, diagnostic usually starts, low boost, test the CAC, low fuel pressure, change the filters and be sure they are on properly, and the right ones, and proper pressure. The air system filter plugged, or exhaust. Turbo seized or malfunctioning, Valve set to tight.
Why is my cat C7 in cold mode?
Somethings going on when it come out of cold mode. You most likely need a set of injectors. If your high pressure pump was replaced due to failure, then it may have contaminated the injectors. The injector map is in cold mode (rich) until 165 deg.

Top speed might be 35 – 40 mph. Need to kinda feather the throttle until the engine temp comes up to then it runs fine. See this thread……
