Diesel tuning for tractor

Hi. I have a question. I purchase the diesel tuning fundementals course. İs this course right for the diesel common rail deutz-perkins tractor engines? 2.Maybe straight pump old diesel engines?

I'm not personally familiar with that particular engine however as long as you're dealing with a common rail diesel engine then the principles in the course will be applicable. It won't really help with older pre common rail engines though.
