Car is N/A. Driving around the city afrs are a normal 12.6:1 at WOT upper RPMs, seeing close to 100kpa. When I go up about a thousand feet in elevation to spend time in the mountains I'm seeing 13.-13.4ish to one and about 92-95kpa depending on the location.

Question is... Do I need to be running around 13:1 at WOT when at altitude or is it safe to run leaner because technically it would be like doing 90% throttle at lower altitude? Say you went to 10,000 ft and your max is 60kpa at WOT... Would it be safe to run the engine at like 14:1 at WOT? Trying to get a handle on this stuff. Thanks.

Just as an FYI, if you have a ms3pnppro, I did a write up how to on how to enable and use / tune the barometric correction sensor and table.

That's the right thought. You wouldn't need to be as rich since it would be effectively "less pedal" in other elevations like you said.
