FM's dyno does read high though. They adjust HP to compensate for altitude (they're at high altitude)- this has the correct effect on N/A or supercharged cars (since they make proportionally less boost with lower ambient pressure) but for a turbocharged car, it inflates the numbers significantly.
This is why stock cars read with normal HP on the FM dyno. If they weren't correcting for ambient air pressure, the stock cars would actually read low.

I dont understand, why would you not want an extra ~40rwhp and ~15 ft-lbs after a dynotune for the $5000 you spent on your kit?
I'm very fortunate by finding this forum before any other haha.

I know it's hard for a lot of you to phathom, but I know a lot of guys that do most of their tuning on the track and street and never feel the need to go to a dyno. It's their choice and that how they like to do business, that doen't make them morons. I'd be more willing to slap a moron tag on a person that thinks there way is the only way.

Which the original poster acknowledged may be the case, but is not that concerned about that. The guy has 3 atoms and the MSM he has is somewhat of an after thought for him, he just wants to slap on a decent kit that's easy to install, do a little tuning on the street and track and let the chip fall where they may. I know that's a hard concept for many of you because your maita is you primary performace car, but not everyone is that way. When I had my mustang project, I'd toss an occasional bolt-on on the MSM and be on my way, mot to concerned about the exact details or numbers. And as a good example, my mustang made over 600rwhp without dyno tuning. The guy that tuned it did a most of his tuning that way. When I finally did take it to a dyno, I picked up another 30 rwhp with the dyno. That 30 hp didn't make that much difference to me. The car already exceeded my primary purpose. I've been around cars for a lot of years, long before I ever bought a miata, and I can tell you there are guys out there that can do a lot of things well using what use to be conventional means, but new technology like dynos don't always translate over to the way they like to do things. He'll I know guys that can tune a damn carbed turbo car on the track, and the dyno queens are still chasing him.
