Is a good reputable octane boost additive sufficient for boosting octane and running the 91 tune? Say from 89 octane. Thanks

Thank you

I have only been running 91 or 93 octane. I was just wondering, but I figured it was a bad idea. I have been getting knock retard only at very low rpms while cruising. Almost right before it wants to shift down. The highest number I have seen is 6. My air/fuel command ratio is 14.63. Just wondering ...

Can you run 87 octane on the 91 tune without any problems? Also would there be any benefit of using srt fuel injectors? My plugs seem that they are running lean.

I have the options to make adjustments to tire size. I never used them though.

Great! That would be to have those options. Another thing I was wondering. Is it normal to lose cruise control functionality after installing the 91 octane tune, mds shut off and throttle booster turned on?

It’s just taking awhile and the car will shut itself off after a half hour then I lose my Bluetooth connection with it so the update doesn’t finish. That’s why I was wondering if the vehicle could be running during the update. I ...

Thanks. I ask because I don’t see options for lighting control and a few others. When updating the predatorx it said I had 95 updates but the Durango will shut power off after around half an hour. So I keep losing Bluetooth connection with the unit. Can I update the unit with the vehicle running? I ...

I just purchased the predatorx and am now waiting for the new pcm. Will I need the new pcm before I can change light settings for dtrl and fog lights? Thanks
