Here is some food for thought for the OP.
Chevron 94oct is a OXYGENATED fuel intended for high performance clean burning modern car's. In a 2 stroke it can eventually cause detrimental damage to the piston's. Its a bad fuel for any high performance 2 stroke.
In a bone stock Nytro (NON boost) it is ok.
In a boosted Nytro or any 4 stroke on boost, 94oct can lead to top end damage. Chev. 94oct will cause the combustion chamber to run extremely hot.
The best fuel to run in your new sled is 91oct. with a mix of race fuel IF NEEDED. An O2 sensor and guage will let you know if you need it.

As for elevation concern's, turbo engine's make their own atmosphere and your elevation will have very little effect on it's ability to burn the fuel safely or the power it make's......unlike a N/A engine.

Drive belt's on these sled's go the long distance and are cheap to buy. Mostly because Yamaha has one of the best clutching system in the industry, even after a hard pull these clutches see very little heat...ever.

As for boost adjustment, MCX 270 base setup is NON adjustable as previously mentioned....but an adjuster can be installed, your might have it, you would need to check it out.

Hope that help's shed some light on your sled.

A tib bit on ETHANOL. Most all pump fuel have about 10% ethanol in it, it generally say's so at the pump.
Is it a big deal? It is with the 2 stroke boy's as ethanol can dry out your main crank seal's and cause an air intake leak. But it is pretty hard to 100% avoid it and it it's not something that happen's quickly.
In the case of these modern 4 stroke's, ethanol will have little negative effect as there are no seal's to damage in the engine like the 2 stroke.
The big scare with ethanol is it does attack rubber..(seals) with time.
