Tuning at altitude

Hi,

Is there anything specific that can/should be done to make a R53 perform better at 10,000 ft? Or does the O2 sensor feedback adjust the air/fuel mix accordingly?

Thanks

A/F is going to be regulated by the computer no matter what altitude.

The typical performance mods that everyone does would work at altitude...you just won't get as much performance due to the altitude.
