BTW, when you did these runs, how did you maintain your control group? Were they all on the same dyno, in the same conditions? If it was the same dyno (such as Dynojet), did you keep the car in place the entire time with the straps not removed?

Yes, same car, same dyno, same tank of gas, same atmospheric temperatures, same coolant temperatures, car was not removed from the dyno.
It was done on a Dynapack so there are no straps to remove or alter the test results. Dynapack is a wheelhub dyno. And it is the most repeatable of all dynos.

I agree you could probably make some conclusion between the Baseline and MREV, but there is no usable information regarding MREV vs. MREV+Spacer.

The Dynapack has an accuracy of +/-1% on its measurements. 1% of 270hp is 2.7hp, so when you add your error bars, you'll see each case is virtually identical.
