Is it a fairly new dyno or has it seen is better days and parts that are worn?
If any of these factors are true then why would someone in, lets say Washington State, say that another persons results in FL, or wherever, are higher than they should be?
The dyno machine has a correction factor that are suppose to be used by the operator when tuning for elevation and humidity. Some dyno machines are stingy and some are happy with results. Additionally each engine will produce different power based on assembly and breaking.
Engines that are built the same are like fruit, they look the same on the outside but some dont always taste the same on the inside
Best answer is to compare dyno results from others on different forums to get a general idea of the possible results from what your building. Then speak with several engine builders to get the input from what they know
