DA, elevation, temp, etc all plays a role in determining what a car will make on a given day. Find one dyno and stick with it it's strictly a tuning device and the most accurate measurement is taking it to the track. Unfortunately, AAA is still closed so irwindale is your only option. Both have their issues, AAA is a notoriously slow track and irwindale is a notoriously fast track. I've NEVER been able to replicate a run I made at irwindale at AAA.

There's also just jack asses who don't calibrate their equipment. But see the data table above, the spread is not so big and has been my personal experience going between two reputable shops. Don't modern dynos software adjust for elevation at least to bring everything to sea level. Thought I remember that. But yes an engine can vary a lot but, honest 530 to 450 is a shit ton of difference, to the point I suspect either a) the engine ain't making that much power or b) one of the dynos is not calibrated correctly. Of course it could be a "run" of all those factors adding up to a big difference.
Anyway, what's most important is that it does what he wants in the context he needs it to work. At the end of the day, it's all about ETs.
