Yes-- especially when you have to work on a customer’s bi- turbo that he thinks is really something special, but in reality is a roached- out turd.
If you want a real challange get hold of a Maserati wiring diagram-- I guarantee you’ve never seen anything like it. I had the pleasure of doing so when I had to repair the power window circuit on an '81 Quattroporte.
I hated working on Ferrari’s too. Complete clusterfucks. Give me a Porsche anyday.
