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.

I'm only going by the reputable dyno runs from well known tuners. The problem is most of them are spread across the country. Different geographical location play a big part.
When properly set up a mustang dyno needs to be loaded to the vehicle that its placed on, so different cars will have different splits. I'm not saying it is or isn't probable. Just what i've seen
