It runs perfectly fine on 91. If it's extremely hot and you will be tracking the car you can throw in some octane boost without issue.
Hey, how are you? I was wondering if you could help me or give me advice on something. I have an Gen 5 ACR 2016 and I really want to get the VE head an cam package but at the same time I was thinking it wouldn’t be worth it if I’m running it on 91. I live in LA, and 93 is not provided this area as you might know. So how’s your car running with the package? Hope to hear from you soon. Thanks, Ali.
