I'm leaving for Colorado tomorrow morning and I'll be driving the Evo 2k miles from sea level and 93octane to about 9k feet and 91 octane. I was planning on re-tuning as soon as I got to 91 octane territory but I've just found out that my tactrix cable isn't working . Now since I don't have time to trouble shoot the cable/software, am I ok to drive out there on my current tune? Obviously I wouldn't be beating on the car and would try and add octane booster at the fill-ups (even though that probably does squat). Once I get out there I will be able to use a different car to get around so I'm not worried about not having time to re-tune.
Thanks

 

Less air so it should just run really rich, not a big deal if your not up there forever.

 

Going up in fine going down is the problem area :P

You probably are going to loose a lot of boost pressure going up that high.

 

Ok great. Ya, I'm not too worried about power. Just don't want to knock all over the place and break something ;-)
