i am wanting to fuel inject my small block chevy. i am looking for feedback on these new self learning efi kits on the market now. Has anybody uses one or know someone who used one? want a system i wont outgrow if i build another motor. these kits say they can handle up to 550 hp. i currenly am in the 400 ish hp area but have plans for a 500ish motor in the future and dont want to be hp limited by the injection, so it sounds like one of these kits would be good for me but havent ever seen one work in person.
