You are at 670m in Edmonton haha. Yeah it makes a huge diffrence being up here vs sea level. FI does not suffer near as much as our poor NA cars

I will come for a road trip!! I wana feel what my car can really do! Allthough I am not sure it will run too well down there without a retune.

Definitely the altitude. I drove my car to NC to drive various driving roads there. I went up Mount Mitchell which was up to 6,578ft and the car was pretty gutless. I had intake, header back, stage 2 tune from delicious. You can calculate your density altitude which really determines your performance. You could be at 7000ft field elevation but your car could performing like it was at 8000ft due to non standard pressure and non standard temperature.

Yeah, that could be a factor too.

Yep, brings to mind when I drove my fully loaded (plus passenger) NC, miata, up to the top of Pikes Peak (elevation 14,100 ft); it made it (thanks to hi revs and lots of gears).

However, ol humfrz was moving pretty slow up there .....

Yep, OP, I'll buy into the octane difference, plus higher altitude, plus warmer air, plus dryer air ..... (dryer air - see who is payen attention .... )

You lost like atleast 30hp bro, Air density is like 85% of what you had @ that altitude.

I've done the math, it's: HP Loss = (elevation x 0.03 x horsepower @ sea level)/1000

So 7000 *.03*200/1000 = 42 HP lost, seems a little high to me, but im sure there are other factors in there.

It's actually really cold in Santa Fe right now—colder than Boston. Air is definitely drier and thinner, though!

Did you move down for good? I miss NM.

To my knowledge, the automatic transmission does whine. It's a normal trait of it.

did you put the wrong fuel in it???

I'm moving for good at the end of January, but actually won't be there full-time until April because the gf has a gig in LA for two months. Pretty excited to be going back, though.

I mean...

Definitely not. But it is 91 instead of 93.

[Crashdummy]

A few months ago I drove from Milwaukee to Portland then back, noticed a big difference in MPG and performance once I hit the higher elevations. Ran 91 to 93, no ethanol all the way.
