Ironically I just got back from a road trip which included elevations of up to 5-6k which are not even as bad as some are reporting here. The car was a DOG relatively speaking and I thought of this very issue. Mine is a FBO with 95 octane which is a rocket ship at about sea level where I normally live but it was just painfully slow.
It was really bizarre as it still sounded loud just like normal but you would stomp on it and it just would not go like it normally does. I just don't think the m3 or any NA car is the way to go if you live at high elevation. It is the one arguement I could make to go for a 335 unless you wanted to suparcharge it or were willing to which not a lot are. I personally know I could not tolerate the m3 at the high atltitude so a supercharger is just a must but its all about if you can tolerate it or not. Also another post in terms of wear and tear. Just because there is less oxygen and thus less fuel, it does not effect the wear any less or more. The parts still move for the most part in the same fashion, and in terms of RPM"s at the same speed. The more power does not increase wear on anything within reason so its really a wash and not any difference in wear. Gas mileage also does not change as the car uses less fuel with less oxygen but loses volumetric efficiency so it balances out |

Welcome!
If you don't think you have power now wait until the summer when the heat soak hits Hope you're enjoying the sand blasting weather we're having this week-end. Next time I hear someone say the NM climate is "mild" I have to make them eat a pound of dirt! The M3 needs a turbo kit, maybe you'll be happy to trade to the M4 when it comes out |

I just spent the whole afternoon spitting out dirt, squinting my eyes, and covering my nose and mouth. This dust and sand can't be good for our car can it? I may have to change my intake filter after a couple of months driving out there
P.S. Man congrats on the new car, sucks you had to let her go though. Quote:

Happy wife. happy life.
I think she might be already sold on the idea, she even mentioned that it was rather slow when she took it for a spin. The scare factor is now missing. As soon as I find a job, I will drop the $$$ on a kit. So here's to a new job in the near future... Quote:

One good thing is that you're much closer to ESS. Go for a long week-end in Phoenix and come back with a bunch more HP |

Just an update, after trying the 100 octane gas, I'm pretty sure it had little to no difference at all. Problem I think is that my timing are not set to take full advantage of the 100 octane. It looks like I have to play with the big boys and drop some $$$$$ on a SC kit. Phoenix is not that far off, I might drive down to ESS one of these days.
On a side note, got into some incident the other day. I was driving on i40 and the truck in front of me had some ice buildup underneath the wheel well and around the cargo area. It was warmer in Albuquerque and I am guessing the trucks came from a much colder area. The ice started to melt and a big chunk of it fell directly in front of my car. My reaction time was not fast enough to swerve out of the way, but in some ways I'm glad I was slow to react. If I did I would have slammed on the car on my left and right. I ended up running over the ice and it took off my undercarriage completely clean. That's not the worse part, the impact caused my paint to crack and broke the lower grill. I'm glad the radiator is still in tact with little to no damage. Now, aside from the crazy Albuquerque drivers, I have to worry about ice falling off trucks.

94-95 octane allows you to hit your max timing target of 32 degrees advance so even in optimum conditions and even with a tune, 95 is enough. 100 offers no added benefit.
Given your cylinders are filled with less air and fuel, your chambers are likely staying much cooler than normal and timing is not being retarded at all, even with 91 octane (normally 91 is not enough) so as others say, your problem has nothing to do with octane defiicit. You need a supercharger |
