That is the other thing people dont understand (well, many dont)
take 10 identical cars
bolt on identical mods
dyno all 10
10 different whp numbers. Varying up to and often over 20whp from highest to lowest.
Heck man take all 10 BONE STOCK and dyno them. 10-15whp differences are not super uncommon.
