Also you'll have to modify your driving habits in stop-n-go traffic as the OP has already noticed. Whenever I make a short roll and back to neutral I blip the throttle to keep the motor from stumbling/stalling.
03Silvaevo what you are describing is pretty normal for the cams you have. Have your ECU tuner bring the idle up a bit and adjust your driving habits to compensate for the lack of vacuum and you'll be fine.

I apologize... I didn't compensate for the already low vacuum at this elevation... Is what you're experiencing with the GSC's also true for the Cosworth 272's (M2)?
I guess I've been reading more about lower elevation people (without paying attention to location) having better results with idle and such.
Thanks for your feedback and input... Makes total sense...
