I have added the M62 and M90 specs to the Techinfo section on the main header bar under the Specifications sub-category. I have also added a little information on the
effects of temperature, humidity, and pressure on air density. There have been alot of questions regarding these subjects bouncing around in the Performance, Mechanical and Maintenance, and 1992-1999 forums. I felt it would be a good idea to put it all in one place.

If anyone finds any errors, please let me know!
