AND, I want to add...adding more AREA under the dyno curve increases your AVG horsepower which is a GOOD thing. It's not all about the Peak increase. We are too prone to concentrate on the peak power number when we only spend a fraction of the time at that peak RPM/HP. Area under the curve is VERY important.

Another thing to keep in mind, when they say "PEAK Gain" really they mean the highest gain between the before and after at any given RPM (again could be at 3500rpm, 2500rpm, etc...). I'll say it again...the devil is in the details...or wording
I think I understand it all now. Thanks for the details, information, and explanations.
