High altitude and intakes
So I will be moving to Denver on Wed and picking up my new 5.0 on Friday. I am curious if it is worth it to get an intake and tune since I will be at least 5k above sea level.

Lower Atmospheric Pressure means thinner air but does that mean you need less cfm?
My thinking which could be wrong. Thats 16% less oxygen per cfm at that altitude. Also a 16% drop in pressure results in a 9% decrease in flow. That would make me think you would flow only 76% as much oxygen for a given size intake with the same pressure drop. This would seem to make a larger intake more desirable. Again Im not a physicist so may be totally misinterpreting the effects.
I would contact Jay Tucker at JLT as he has always shot straight with me even when it wasnt in his own interest.

Sweet thanks for the info, I will get with him as soon as I get to the states to see what I should do. Just glad I am driving the car for the first time in denver so I dont notice the nasty power decrease.
