I have been doing a lot of research to this new to me 225 EFI and there is a ton of info out there. SN OT749027. I was thinking of playing around with it and seeing if I can gain a little horsepower. I searched and found the fuel injectors from a 225 and a 250 seem to have the same part number. I read in other forums that going to a 250 efi controller will give a boost.
So, would this be correct?
