  • standard internals + K04 problem

    Hi guys!
    I decided to go for the astra opc's bigger turbo with standard internals.
    All I have had done on my car so far is:
    - milltek 3' full exhaust
    - forge intercooler
    - dbilas flowmaster
    - bosh bigger fuel injectors
    Nothing else.
    I gave the car to a private tuner. He installed the turbo, mechanically seems all right. The big and lasting for a week problem is programming it. They say they have problems with turbo boost or pressure keeping it stable...
    Andybody who has had it done or is into it, could help? could it be this hard to programme it or any mechanical modifications are needed?
    I am beginning to think that I might not have it done;/
    Cheers

    Could be the actuator? Have they set it properly.
    Also wouldnt reccomened running that turbo with comp pistons but I dont know too much about the bigger turbos in regards to internals.

              The only tuner who can onsite tweak a map is Ryan at Regal the other tuners have to go back to their suppliers.

                    You should try a electronic boost controller or a manual boost valve to see if the boost is stable.....

                      i was thinking boost controller and maybe MAP sensor too?

                        Maybe it's the Bosch injectors. Are they plug and play? If so, then the standard recommended astra Vxr injectors are 480cc and the plug and plays are less CC so maybe it could be to do with that. Eds map is for the 480cc

                          How does the EDS come in to play if you're getting it live mapped

                          (not hijacking, OP might not know either )

                            probably this is what is going to happen - what they are going to do..
                            I am not from England, just order the items to my country, and have to count on my tuner.. Just didn't think it would be such a problem with my car - this is what they also say. I would like to know if such problems have occured in any of yours car while modding, or may I expect no big turbo applicable to my car;/?

                              All the cars i know are using 3.5bar map sensor.
                              You should try a boost controller to see if you can adjust properly the boost even tho you should make it wthout controller.....
