Default Rs turbo 1.9 American block .. should I go MFI or EFI ?

Hey guys, I have a 1.9 American block with forged pistons, apr bolts, apr head studs, Burton stage 3 big valve head, Piper t285 cam n lifters,
Garrett stage3 t3 hybrid turbo with .48 housing and a
Grs Intercooler .

The question is do I keep the mfi set up and how restricted am I for bhp tuning wise?

or do I buy the efi setup as I have both heads?

does the mfi open up a much larger performance options?

Hi mate not really sure on the restrictions but I ran a 1.9 tall block in my s2 great engine it was built by mark at grove garage hornchurch Essex and mapped by the late Ahmed bayoo when speccing the build efi fiesta turbo head and ofab edu was on the shopping list it made around 270bhp and was very torquey I'm sure if you give mark a call he could tell you the restrictions but I'd say efi is always going to be a step up from old tec

Efi all day long. It's easier to tune.
