Mainly - Ark over F.I. - because of the time it takes to get it - the Ark sounds as good (if not better) and I won't have to wait 3 months to get it.
But also because I was thinking I needed to NOT run the car much without a tune, after the hfc install.
Someone (?) told me I would need to change injectors if I went with the manifold swap... didn't research it for myself - but will definitely look into that - now that you mentioned it :-)
I do all my own labor - but I'm not very savvy with all the tech stuff - tuning & all that - never had it old school lol
