Well no, at WOT you always want an AFR in that range, it kinda depends on the engine as to whats best and I've seen lots of differing opinions, but without EFI its not like you'll be able to tune for 13.0 vs 12.8. If you aren't at WOT its fine if your AFR is higher but you definitely don't want to be WOT in the 14s
