What fuel to use after PI Headswap?

[CanadaStang]

Can I just use premium fuel [92 octane] after doing the headswap? Or do I have to use octane boost as well?

92 octane will be fine.

You can use 87 octane if you wanted to and it would work fine. Owners manual suggets using 87 octane but no matter what octane you use it will be fine just so long as it is unleaded.

the 92 will be fine..u dont want to run your car on anything less than 89. i have found the regular to detonate due to the higher compression ratios. i would suggest the 92 octane, if you like to have "fun" in your car all the time.
