    I've just towed from Maitland NSW to rainbow beach in Qld, same fuel results as tombie, probably lower road speed. But the big thing I noticed was how well cruise control now holds. I'm basics inclines within 2kph of target, with bigger hills, I just manually dropped back one or two. Held within 4kph.. Didn't touch the throttle. Very impressed.

    I've had the EVC throttle controller out for since I had the tune and the response has come back now all the relearning is done. Just without it as being so harsh as it was with the EVC fitted.

    Excellent result

    Yes actually

    Melbourne-ish there's Angelo at Autofarm+Engineering they're in Kilmore East.

    Adelaide there's BigJon at Mitcham Motor Garage in Hawthorn.

    Brisbane talk to Joe at LRP Automotive in Virginia.

    We're in discussion with a few more workshops to try & get more coverage, but you know it takes time to find good people.

    The fact that it can be done near Melbourne now is very tempting , last year did a long touring trip with the 2.5 ton van , the car went well but I did notice it was certainly lacking every now and then especially in the transmission shift points.
    Roughly how long does it take to do engine and trans tune?
    Should the trans be serviced before the tune? It was serviced about 40,000km ago
    Does the engine tune remove the EGR or alter the system operation?

    Pretty keen to make a great car even better

    Do it…

    We just had the RRS tuned 3.0l (both Engine and Transmission) and it’s fantastic.

    The D4 was done some time ago and again, brilliant - how it should have been from the start.

    About 2hrs from start to finish, but needs to be done late in the afternoon so the time zone lines up with our man.

    It's not a must. Servicing the transmission is no more or less important when tuned than with factory calibration.

    With 3.0 our usual approach is to keep the EGRs fitted and functional, the way they function is altered though.
    Stops the soot & crap coming in, but still bleed off manifold pressure when you get off the throttle.
    As the kms get higher on these things we are seeing more EGR problems popping up though, so you might need to decide which way you want to go with it.

    Transmission Tuning for JLR ZF; 6HP26, 6HP28, 8HP70

    Just watch yourself overtaking!!!

    We got caught behind the most inept bunch of shed draggers following a triple sitting on 80km/h with 2 other inept car drivers behind them.

    Not one bickie dipper left more than a cars length between them, and not one considered passing in over 5km.

    So……

    Flick to Sport, kick the pedal and we’re out and off!

    2 cars, 3 car/caravans and a triple RT…. Done EASY.

    Vehicle stable like a rock, look down and see an (alleged) $1.75 Transmission Tuning for JLR ZF; 6HP26, 6HP28, 8HP70🥹

    Quick dab on the brakes to save the licence.

    Damn the thing hauls arse!
