    mate the dealers know jack **** about anything other than what's in the sales brochures
    there was a thread about the altered tune for the my17 ls3 awhile back and some one posted a link to the article,
    i would think a good reason for holden doing it would be its the last model.
    my wife has a 2016 ls3 and i own a my17 ls3 and the my17 ls3 is more responsive down low,
    even my wife noticed the difference between the two cars when the right foots planted

    Does anyone have reliable information on different tunes?

    Or is it just forum opinions via the butt dyno?

    Links or articles?

    i think from memory it was a test from car guides or one of the motoring press on a ss ls3, and they quoted holden engineers had increased low down power tune for the ls3. power output was unchanged overall , just a bit more urge down low, do a search on the forum its on here some were

    Any one know if pre MY17 models can get this tune flashed into their vehicles at Holden?

    Earlier? Yet the peak output is at exactly the same revs as the MY16 model?

    The claim sounds as genuine as brockies Polariser. Maybe it's got nothing to do the the ls3 tune. Possibly different diff ratios?

    A change to the diff ratio will have a much wider impact and therefore be easily noticeable compared to changing the tune to deliver more torque at the start of the curve.

    I'd go with the change being in the tune.

    Possibly just relaxed the tourqe management a bit.

    I'm not understanding your question here.
    Why wouldn't software be able to tweak something at one point in the rev-range (&/or load) without affecting it at other points (&/or loads)?

    i am no expert with modern engines but its not like working or turning a old carbed red six or 308, you can make changers to mixture and timing any where you want to on new engines.
    i believe with the software on today's engines you can alter mixture, timing ect at any point in the rpm range .
    so to gain more bottom end power if you can richen up the mixture and give it more ignition advance in the lower rev range.
    the engine sees only that change in the rev range , the overall power remains the same

    The specifications are identical for the MY16 and MY17 at 304kw@6000rpm and torque at 570Nm@4400rpm. If a tune is altered for better low down power we will either see maximum torque of 570Nm at a lower rpm or maximum power at a lower rpm. Also no doubt Holden would be letting the press know for extra marketing blurb and cache along with gloss black interior trim and mirror caps.

    Similar to the update Holden did with the manual L76 to L77. Power was status quo at 270kw but in the L77 it occurred 100rpm lower.

    did you read the article, holden engineers did let the press know .;)
    you can tune in the power curve to come on and start a bit earlier, for more get up and go , this has no effect on max torque or kw power at rpm.
    its just increasing the power curve

    Guess I am cynical with "getting something for nothing". So what's the downside of having this power/torque early in the rev range?

    Needing to spend the time to dyno-tune the engine such that it gets this extra low-revs power (read “initial throttle response”).
    Take it too far & you could get pinging if it’s too hot.
