It's unfortunate that too many "in-the-know" enthusiasts are solely concerned with peak numbers. Obviously, area under the curve gains are what we feel when driving. Auf Deutsche's provided his dyno sheet that showed a mid range gain of ~50 whp over stock which increases to about 75 whp in the upper rpm range. These gains aren't hype, but rather substantial butt dyno gains.
