Does altitude affect my carburettor?

I was going to upgrade my main jet from a .045 to a .049 ( a tip I found in an old post), but Fabio at Vespasupershop told me that with the altitude of Colorado, I should go a size or 2 down instead of up. He says restricting the fuel flow will lean out the fuel and give me better acceleration and possibly top speed (because of the altitude here, about 9000 feet above sea level).

Any thoughts?
