Where do you start?

Thanks for posting, very interesting stuff! After having read text only descriptions of some of the systems, having the diagrams for reference makes it much more understandable. The engine manual and the sophistication of its construction helps me understand why it will take a while for an aftermarket supplier to come up with a good, functional electronically engineered HP increase! Who can do that sort of thing, an ex-factory programmer.....? So complicated to me. I will be very conservative before I jump into buying engine tuning changes. The warning message on page 75 concerning the replacement of the DME control units has to be concerning for someone attempting to alter them for tuning purposes.
