Here's the thing ... it doesn't matter. For some reason a lot of people have become really hung up on dyno numbers the last few years and have completely missed what the purpose of these tools are for.
A dyno is simply a tool to measure the change made to a car compared to a number taken before the change. The only time two dyno numbers are useful for comparison is when the same car was ran on the same dyno on the same day without any drastic atmospheric changes. Outside of that context, all you have is a random point of data that is not comparable to any other random points of data.
This is why you will see dyno sheets on stock cars varying by 30-40RWHP.
