	I just *knew* I might be on to something! :)

	The timing is the big one for me, it means adding a Weltmeister chip does
more than changing the fuel maps; it can change timing too.

	I was just going to ask you how you liked his book but it looks like
you've already answered the question for me. 

	I'm a bit curious, I remember your posts a while back about your
adaptation of the Saab boost control system and I was wondering, is your
745 faster than your 765?  I must thank you for something else entirely; a
month ago I went out and bought a new camera. I traded in my old (and very
heavy) Minolta XG-1 and lenses and hardly had to pay very much at all for
the new camera. I noticed the guy pulled out your book when looking up
prices.
