High Altitude Emissions

I recently sent in for my truck options via the DC website. I was looking them over and noticed this one:



NBHP - High Altitude Emissions Tracking



Does this effect performance? I bought the truck in Colorado but live in Missouri.



Thanks

Ask dealer if they have a low altitude reflash.

I have had the truck in for the latest 04. 5 reflash here in Missouri. Do you think they reflashed it to the low altitude?

D/C can not change the configuration of the ECM only update unless a new ECM is used which comes empty than the referance number off the data tag is supposed to be used to choose the software pkg.

I wouldn't sweat it anyway. I have bought two 3rd gens in Minnesota and driven them in Colorado, and have bought two in Colo and driven them in Minn. Can't say I've noticed any difference in any of them.
