Same thing will happen to a car. If I drive to sea level, my car will notably increase it's performance.
Where you are you will likly need more engine then the OS 91 2 stroke, on the****************** site we have some people who live in Denver and they have to use more motor.
I would guess that a Saito 115 would be the best choice

Normally the Saito 100 is the perfect match for the Swanyshouse Mojo MoAss 60.
The reason I want to use the 91FX is because I have one lying around. If that engine wont allow me to hover the MOJO 60 then I have to consider another option.
