Corky Bell's book rules the world...
But I've ordered Jim Hartman's "How to tune and modify engine management systems" too..., and I must say that this knowledge is the really brilliant!!!! I would say that theese two books are absolute necessity for the tuners....
But Your find is very nice too - all basics, all theory, nice, nice

It contains really much info.
The Bell's book has also some basic shapes of designing manifolds too, which is very important for me...
