Low 14s, maybe a very high 13 in great air with great track prep and good tires (and a tailwind) and depending on this "tune."
I always hate it when people talk about a tune, 'getting a tune,' 'chip,' etc. It's not like a set of 4.10s, when you get a set of 4.10s you get a set of 4.10s. When you get a tune, you're getting a set of parameters that are only as good as the person who made the tune, and if it's a mail order tune it's even more variant...
