A course doesnt give you experience though.
I perish the thought that someone might take this course....then run about claiming they know how to tune cars.
I dont believe that tuning of this nature can be done with a 1 day course...or even a few weeks. It takes years of experience, firstly understanding how an engine works and what it needs to create power, and then also how all the electronic systems work alongside and in conjunction with the engine to allow the user to take control.
I dont care how many courses someone goes on. If they dont have the experience working with and tuning engines....no way in hell would let that person near any engine belonging to me.
