    Re: need some more help

    Post your settings from the profect b, is it a spec II?
    Also need to know what turbine housing you have on the T3 and what stage it is?

    What are you using for a wastegate? What displacement and CR is your engine?

    57 trim is the compressor side, need to know the A/R of the turbine housing should be .48 or .63 or .82 perhaps.

    List the settings of your boost controller, I have the same one and its a bit of a challenge to setup.

    Is it this one? Your settings didn't make much sense.

    I'm running a T04E '50' with .48A/R stage 3 T3 on my M10, which is 2.1L and 9:1 CR. I get 12 psi before 3000rpms. Have you tried turning off your boost controller and letting the wastegate spring handle boost? I assume you can adjust the spring pressure on your wastegate. It's possible you have a leak either at the wastegate or perhaps in the pressure tubing to the intake manifold.

    Re: try even switching the lines

    There must be something leaking, hard to say which side(exhaust or intake) though. Can you hear it trying to spool? induction sucking sound? That might indicate if its leaking after the turbo's compressor or in the exhaust. Do you have a blow off valve or bypass valve?

    i have a tial blow off valve
    i cant hear it trying to spool could it be b/c of the 4.10 ls diff its not getting enough time to start spooling
    but it should spool if in neutral and giving it gas

    Re: try even switching the lines

    Wont make much difference, it wont spool in neutral or with the clutch in as there is no load on the engine. This only happens in cheese movies ;)

    The higher the gear the easier it will be to see and hear what is going on, although the speeds quickly get to illegal levels...
