Well, I went on to read the rest of the manual. This is definitely a great guide to get you started and at a price much less than some of the DVDs out there. The explanations for the tables were pretty well written and thought out. Comparing the HP tuners to some of the other platforms out there, it is a shame that they do not do the 1989-2004 Mustangs as the software I have used previously is not very good and the logging software is quite pitiful compared to the HPtuner logging.
Overall if you want to get a good grasp of what various tables are necessary to tune and become familiar with this software, this manual is quite helpful.
