You can to a degree, but not via dyno tuning. By altering the spring rate in the waste gate, you can alter what boost setting you run at. This can involve alot of f**king around and for all the time you waste, I would just go and by an electronic boost controller and be done with it =]
You CAN adjust boost WITHOUT a boost controller. You do not NEED a boost controller. Setting a boost level is quite often done by the tuner via a dyno. The dyno itself cannot adjust boost, its up to a person.
Two types of turbos. INTERNAL wastegate and EXTERNAL wastegate.
Internal is adjusted by the actuator. This is adjusted via the arm that opens the wastegate. this can be adjusted longer or shorter to adjust when the gate opens or closes. You do not need a boost controller.
External is adjusted via the spring inside it. You can get 5 psi, 7, 10psi etc. You do not need a boost controller.
thank you very much for that. thats what i was after. so once i get my car tuned, the tuner will be able to either adjust the boost level to an aggressive level or a safe tune running low boost? just really shady on the whole thing since im new to boosting. thanks guys.
Alot of oem turbo cars are internal gated setup, as they are compact and can be low mounted and cheaper to manufacture.... But in saying that, they are electronic or have boost restrictors to limit the boost, but since u are asking about a turbo kit which is aftermarket, it will most likely come with some sort of a manual boost bleed, or simply run off the actuator to restrict the boost.
If ur after a quick fix, any simple manual boost bleeder would do the trick!
No need to go EBC, cause ur not tuning it for track or dyno queen...
