After taking the ASE Engine Performance ASE test, I failed it by four questions. I will have to retake it in a few months. Nevertheless this book gives you a great addition of knowledge to add on preexisting knowledge. If you are planning on getting this book without any prior understanding of Engine Performance and just passing the test, forget it.
The fact is that most of these questions will not be on the ASE test. There are 300 practice questions in the book. A lot of them are good for info. And some of them are not even worth looking at. Common sense questions that you will never see on the test such as " what is the first step in the diagnosis process ". Knowledge such as this is basic and there are a few questions like this in the book. But trust me, they will not be on the actual test.
There are a few areas it falls short at. But again with such a large amount of questions and explanations, you learn quite a bit. So I would not give it a bad rating. One area it falls short in is scan tool diagnosis. Such as live data diagnosis. Even though I was already prepared for these kinds of questions, it was not thanks to this book(I studied various online practice and study test). In this book there are few scan tool diagnostic questions that involve interpreting live data. But on the test, you are bound to see at least 4 or 5 questions about interpreting live data.
Another area it fell short in to me was Emission controls. There was not enough thorough symptom and diagnostic info on the EVAP system or questions. I was seeing questions such as " a customer complains they cannot fill the gas tank pass half full ". There is no info on this kind of symptom in the book. Of course I dont know if that counted towards my score, but there were two similar questions like this one. So I feel it should have been covered.
The Engine Performance ASE test has a lot of diagram questions. So I also feel that there should have been more of those in the book instead of putting those simple ones. Electrical diagnosis is one of my weak points. And there are a few questions on this, but I feel there should have been more. Last but not least there are some disputable questions and a couple of small errors. Im not going to go over the small errors I found.
Regardless of the cons, for the money it's well worth it to increase knowledge and understanding of this subject. I would definitely recommend it to anyone planning to take the ASE test. And I will buy the other versions as well. In fact I bought the Engine Repair version and I passed that test. But of course Engine Performance is a bit more advanced.
