I think that setup would be over 120 HP and more than 30 lb lighter. I have almost 200 hours on my 912 ULS with the EFI. Doug(Floog) has probably even more.
Probably save money too depending on if you got a used 912ULS. My 914 has an SDS injection setup. Also a Canadian guy in Calgary. My engine will be easily good for 125. I can run over boost if I wanted too as well since I no longer have to worry about having more boost than fuel pressure. I probably won’t go that route but it’s an option
