How much power increase do you actually get from just the efi swap. There are definate benifits to efi but I don't know if power is one of them. I have an 84 with an efi swap and its far from feeling powerful. 36's and 5.29's and it takes all its got to go freeway speed. The swap was done by a previous owner and I have no idea what condition the motor is in, maybe a fresh 22r would feel like it has power.
