Altitude

Alright guys,

I'm moving from the Boston MA area to Flagstaff AZ for school this summer. Driving my 3rd gen with 212k out there, wondering if I should be concerned about the altitude change, here in MA were at almost sea level and Flagstaff is situated at 7000ft. Should I be worried about re-tuning my ecu or somehow adjusting my A/F mixture for the altitude change?

On a side note, any other 3rd gen owners in Northern AZ? Im excited to get out there and do some wheeling!

Yup 21-24% less power or fuel mileage however you want to feel about it, no matter what. But hey, no rust! Beautiful area - enjoy. :cowboy:

Alright a fellow New Englander!! Truck does just fine out here. Definitely a power loss that can be felt out on these highspeed highways, but you don't need to do anything different.

Hit me up if you want to wheel, I'm just 30 minutes south in Sedona.
 
My girlfriend and I just spent 5 days out in Flagstaff / Sedona two weeks ago. By the time we were getting ready to leave we were both looking for employment opportunities to stay out there! Absolutely gorgeous area and fire roads / unimproved trails for miles out there, perfect place for our trucks.
 
Welcome to Flagstaff!

Living both here and making many trips to phoenix, the power difference, while noticeable, doesn't bother me. But then again I come from 22R power...

I still get right around 19mpg up here in town, so the gas mileage isn't much worse either.
 
3%~ power loss per every 1000 feet you go up in elevation is the general rule. I really notice the difference driving from my house in Wisconsin to my parents in Wyoming (900ft to 6200ft elevation). Better get a supercharger!
 
Coming from living at above 10,000 feet it'll be fine. Sure you're a bit down on power but it's not a huge deal. AZ is great!
 
Barely noticed a difference with my 4th gen going from sea level to 5300ft. One thing you will notice is if you're towing a trailer, it'll run like a dog at 10,000+ for sure

short answer regarding altitude: No.

PS A LOT of us go up north to escape the heat.

Awsome! Yeah I have been looking forward to moving west for quite a while, also excited to hit some trails!
 
If you're going to be laden with your stuff just take it easy going over the Continental Divide. Don't try to hold 70 if she is working her butt off. You'll get there, just hang in the right lanes so you don't tick people off.
 
Like started ecu will take care of everything. Just loss of power. Here my Talon at 400+whp ran low 12s with occasional high 11 at the track. Where people at sea level in the 10s.

But motors last longer and have less wear in the high altitudes.

Based on what? Sounds like an old wives tale to me, given there are so many variables that lead to how long an engine lasts.

Based on my old buddy that has built 1000hp DSM, GTR and Evo's for about 15+ years now. He has seen motors from all over the US sent to him and during tear down anything from sea level seems to always have more wear and tear. Which would make sense with how much power loss we have up in the high altitude.
