I have a 2010 Toyota Corolla S and I just moved from VT at under 1000' to Flagstaff at
7000'. Since elevation can affect a vehicles performance and power due to lack of oxygen
would changing the air intake bring me back to my usual performance? and is that
something that can be done by a computer or would I have to buy a new air intake.
I would try a computer relearn first, locate the ECM fuses and remove them for at least 30 seconds, that will but the ECM back to factory settings, reinstall fuses and then drive as you normally would for about 20 minutes, this will allow the computer to adjust for your elevation and different driving routine. If you still don't like your performance you can try a cold air package or a superchip device but there is only just so much oxygen at 7000 feet that performance increase won't be much.
anu idea where the fuses would be? I'm not looking for a lot of power just what I had
They are located in the power distribution box under the hood. You will not get the power back, it may improve but the air density is just not the same at 7000 feet.
