    When I start to show interest in engines i didnt had a clue but this course has helped me to have a clearer understanding of how the engines suppose to work. Great course

    Great introduction to diesel tuning. Teaches you the basics and leaves you with the right information to speak the same language as your tuner or dip your feet in yourself. As always delivered in nice bite sized sections and easy to understand. Defiantly worth the buy.

    Wish it was around sooner! I've easily wasted enough money on purchasing the wrong crimpers and other tools that I could have used to cover this course.

    It’s worth the money, trust me. I searched the internet for solid info. Lots of misleading information. I have repaired multiple makes of diesels as a result of bad tuning.
