When you look at the dyno charts, if you look for peak numbers alone, you are cheating yourself. The peak numbers only occur in a small time window, at exact RPMs. What really matters is the difference in HP and Torque over the RPM range. That is what you feel when you drive. Think about it this way: Would you rather have 50 more HP for a split second, or would you rather have 50 HP throughout most of your RPM range? Just keep that in mind when comparing dyno numbers, so you make an informed decision. If you would like any further explanation or have any questions, just let us know!
