the reason I ask is because I was involved in a similar dyno test (for different mod) and the first several pulls (10 actually) made power... then power dropped... after a series of cool down and 10 or more pulls in each series (30-40 all together) the power was lower than initial pulls... so it was concluded that the original gains were an anomaly and the end lower hp pulls were the data.

So this part of your post: "idle for about 30 seconds and did pulls back to back until it lost power" is what I was interested in... is this to say you did pulls until heat soak dropped power, then after cool down, a new set of pulls regained power?
