    Took my 2008 Prado in for de-soot and dyno tune for towing. Great result the car goes so much better and is much nicer to drive. Very Friendly and professional service. Will have no problems recommending these guys to anyone as I got the results they told me I would get.

    Had my 79 series landcruiser in for a custom dyno, heavy duty clutch and oil catch can.
    Drove out with double the torque and 40% more power, 90% of the lag is gone and Drew gave great advice on some minor changes I can make to the vehicle to get even better performance.
    I highly recommend ultimate diesel tuning to anyone wanting more performance out of their diesel 4x4. Great service and advice

    Got a 3inch exhaust and tune on my 2015 dmax today. It's like a different car, massive difference in the power, way less lag, sounds amazing. Couldn't be happier. 10/10 would recommend to anyone
