Running base map in high altitude

[Polkaman]

Looking to pick up the Flashpro and run the stage 2 base map for my '18 2.0, just had a couple questions to see if hondata or ktuner is my best path.

I live in Colorado and most gas stations only offer 91 octane. Don't plan on getting the car custom tuned for a while, is running the base map on 91 recommended? Only other mod I have in mind is a mishimoto intake.

What elevation are you at?

[Polkaman]

About 5500 feet

That will be fine.

[Spunkster]

You will probably not see the same gains as at lower elevations and you should be ok to use 91 octane fuel.

Thanks a bunch, appreciate the quick replies. Still pretty new to the tuning world, is there anything I should keep an eye on when driving the car? Such as knock, etc

[Spunkster]

Look at the knock and AF ratio.
