The car is an M6.
The numbers are SAE corrected, so I think that the weather is taken out of it for the most part. I guess every dyno is a little different even if they are made by the same manufacture.
The car has just under 68k miles on it and seems the previous owner took very good care of it (don't know him but everything was really clean and the car has no rattles/etc).
Fuel, lol, was 91 octane (highest normal pump avalible in Vegas) from Sam's club. It seems to run great in all our cars, so I run it. I stay away from places like AM/PM and the like.
Thanks for the response. I was just trying to see what others have dyno'd with the same or similar mods.
