I like that one a lot. There's also one with a Focus on the cover that many people seem to like, but I'm not that impressed with. There were also two books on forced induction that were very well regarded back on enginuity.org, but I have no idea what they were because they don't apply to me
You'll probably want to look them over though. I'm sure if you start a thread asking about tuning books, they'll come up.
