What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

SurfDog

I'm just about to move my Z from the Bay area to Denver (January 20th or so)

Soooo....
how to mod?
1. PSS a/t I think to help with cooler grip. (no brainer)
2. rock bra (vinyl) to Keep the winter gravel off my hood. (Also a no brainer)

Here is my question:

-I live at 9000 feet,
-I work at 5500 feet (Denver Airport)
-My car was last upreved at sea level (San Jose California after a bunch of bolt-ons)

Do I need a re-tune (maybe add a high-altitude, cool air map for Colorado driving)?????

It seems like a good idea, but I don't really know much about that stuff.

Help from any of you tuning gurus would be awesome!!!!
