    Apologies if this has been asked before. There seem to be a ton of threads about it but funding the answer is still a pain in the pass.

    Can we quickly answer this question for the benefit of future people looking for the answer.

    There are several options to tune a car.

    1. Replacement ECU
    2. "True-Tune" modifying the stock ECU settings
    3. Piggyback (Modules that plug into the ECU wire harness and modify signals that go in or out of the ECU)
    4. Sensor Modifiers (Tunes that tap into specific engine sensors)

    As far as I know, only a true-tune is legal as long as it doesn't touch boost maps.

    Is a "true-tune" really the only option in ST for boosted cars? Basically a custom tune?

    As long as it doesn't touch the load tables/boost request tables, it should be fine as I've always understood it. Fueling and ignition tweaks are fine.

    I'm sure someone who runs an turbocharged card in an ST* class will chime in to validate or correct my statement.

    No changes to boost and wastegate tables. Fueling and ignition is open

    Don't forget that exhaust is open so any boost changes resulted from exhaust hardware is open. You'll have to look for how to do it for your particular application, but this means that boost is pretty much open to mechanical exhaust modifications. So in reality, boost is open for ST for most cars - the rules just make you jump through expensive hoops to get it.
