[QUOTE="biturbomg, post: 1282357, member: 22257"] What phase Roush is it? If it is the Roush can tune you will be fine but it will be down an easy 2# at elevation. So expect a 40-60hp drop in power which if the truck is new to you may not feel any differnce anyway. Sound should still be good but wont be as loud as it was at sea level. If it has a custom tune I would data log and have them adjust for your elevation and fuel. If you want more power can drop to a lower upper pulley which is the cheapest easy way and if that is not enough add a bigger lower pulley. My 2013 ran the smallest upper pulley and 10% OD lower and made very good power and about 10# at 6000ft. [/QUOTE]
