CHUNT69-couldn't disagree more tbh, i had mfi on my s2- had nowt but problems with air leaks, dodgy metering unit, fuel blockages, bad cold start etc
had it converted to efi and it starts and stops on the button with no problems so far, power ain't everything

Am with you on that fella am just getting all the bits in now ready for my EFI conversion and with Cossie management
