If your car is still under warranty the dealer should be able to set the air/fuel mix to something more suited to your elevation. My REVO select plus lets me adjust the air/fuel mix. I think GIAC has a similar box. You may want to contact both of them. I was very dissapointed with the results of the ECU reprogramming. Get the exhaust and intake if you can afford it for the sound. It won't add loads of power.
