Honestly, the MFI will give you a head ache after a few days. Efi drives better, is more reliable, more economical and is generally the better all round solution regardless of what ecu you install.
My biggest gripe with MFI is that its difficult to make it fuel properly for 200bhp and cruise at the same time. Ie you end up being rich every where and fuelling properly on boost. Plus the newest KE system must be getting on for 20 years old now?
I went efi and have never looked back. But each to their own etc.
