As of late I've done quite a bit of dynoing, I'm not too bright so I ask a lot of questions. On this forum people say that you need to dyno the same day so all tha variables are the same as to temp, humidity, and barometric pressure. The dynos I use have a correction factor built in to account for this. It has a standard and calculates the difference as a correction factor. when I did mine in Oct. it was chilly that night so it changed the numbers to calculate the diff. it was about 1.5 hp difference between corected and uncorected which just took it at that time and temp. Is this accurate or was someone blowing smoke up my tush?
