There are a ton of reasons why an engine can lose 50 hp between dynos that have nothing to do with dyno calibration.

A well thought out dyno cell can easily be worth 50 hp over a poorly designed dyno cell. Even if the dynos in each cell are properly calibrated, there can easily be a large difference in power.



So XE268h cammed, stock head/compression 340's make ~400hp? Sure they do...

The second reading is a lot closer to reality than the first one.

Tuning tool, yes. Believing the numbers some kick out without proving it with real world performance, not so much. Seen too many dyno tested 600hp cars at 3000-3100# run 120-122...
