I got the book 2 days ago.
$55 is NOT WORTH IT.
$15 is mor like it.
Very very nice color pages.
Very nice hard cover.
Very nice Hungarian cooking tips. Yes, 14 pages of Hungarian cooking. Out of 186 pages, maybe 10 pages are worth it.
To each their own, but I don't need to pay money for 15 glossy pages of DTC codes.
They reference a second book which will be more detailed, that might be interesting, but who knows. I can't say I gained nothing from the book, but I gained very very little. I didn't know how many bits wide the bus was, now I do. It explains a summary of how things work. NOT NOT NOT NOT how to tune your car and very little details on actually how things work.
The Ford manual on CD is much more helpful in explaining things.
This is one more reason why I think MMF and Pro5.0 are totally bias and sellouts.
I am not angry over it, but I purchased the book based on the article in the magazine and I think it was very misleading.
I've gained much more info freely through the boards, people's websites and howthingswork.com type sites.
Good luck, and let me know what you think if you buy it.
