same with the injen, if they dyno'd 280 stock on a DJ, 15 hp is roughly 5%. so you should have seen 5% gain over 258, or 12-13hp.

The problem with that is that you are working under the assumption that power is a linear measure, but it's not. Since it's not a linear measure and since both dynos use different assumptions in calculating power output, we can't compare that way.

What we can say is that, on a DynoJet, expect around a 15whp gain. On a DynoDynamics machine, expect less. I'm sure a Mustang dyno would give us totally different readings as well.
