    10psi spring is recommended for a K04 hybrid turbo. I fear this might be my issue:

    I'd be inclined to agree.

    I don't rate all that Turbosmart stuff

    It's great quality gear but real overkill for a lot of things

    I've got a 10psi in my Astra and WG had to wind it back because it is too strong and causes valve float on mine.

    The recircs have too stronger spring too and cause nothing but fluttering even with their lightest spring!

    Just an update on this. Been working with a tuner remotely to sort my issues. We now have the timing and fuelling much better on the car. Wastegate actuator duty cycle % has been reduced to account for the 10psi spring. A bit more work and it will be 100%.

    So my fine tuning is continuing. Welded in a boss to my downpipe to accept a wideband lambda. Have an Innovate LM-2 arriving tomorrow. Before:


    After:


    Also fabricated a better inlet and fitted an AEM filter:


    Got rid of the monstrosity of an Evoms filter setup and Regals pinholed intake pipe.

    So my Innovate LM2 arrived. Hooked it up last night and had a look at my idle AFR. Their Logworks software is pretty cool too. Hopefully i will log some files tonight
