JB4, Catless DP's, 91 oct, 4000ft elevation, which map?
So I just installed catless downpipes over the weekend. I am running them with my JB4. I live in El Paso TX which is at 4000ft elevation and only has 91 octane fuel. So my question is, which map should I run? I was told that Map 5 (autotune) doesnt work good at my elevation, and Map 2 says it is for 93 octane. Should I stick to map 1? Any suggections? Thanks

Start with map1, log and see how your car likes it then go from there

Map 5 is not good when you constantly drive in different elevations, if your car never sees below 3K feet, you should be good on Map 5

So far the car feels good on map 1. I just ordered the USB cable so I can run some logs and make sure my jb4 is updated

Map 5 will auto adjust. You may want to reset it if you come down the mountain or change fuel blends.
