Greetings,
I just moved to Colorado and was wondering about the altitude...Will it affect my trucks performance at all, and has anyone heard about putting lucus gas and engine treatment in the new f150's. I have an 05 XLT 5.4ltr 4x4..

 

welcome to the west- shouldnt matter at all- im running between 4,500-6,500 feet without problems- if you're racing or hill climbing it might, but standard use you should be fine
