On a stock 2014 Viper how much power can be gained and cost to update to 91 octane and elevation and if I want to add headers down the road what else is needed? I'm not sure my local dealer can will do this for me.

I spoke with Andy Wheeler at Viper Exchange asking similar questions about running 91 and he said the same thing that Mark Jorgensen and Arrow say in attached image from a different thread. Knock sensors will pull timing and car will run fine. However, I personally would not run it like that at the track. You would typically run a higher octane on track days anyway I would think. I never dyno’d with PCM installed, it definitely ran a lot more aggressive and was more responsive. You can look at their website to see all of the gains that can be made. Hopefully this helps. To my understanding, adjustments do not need to be made after adding headers, but I may be mistaken and I would call and check with Arrow, VE or Woodhouse.
