I understand the appeal of a direct FI replacement for a carb but it isn't likely to be as efficient as a complete FI system. As an AMC Jeep CJ7 owner, I've dealt with the nightmare of a "feedback carb" which used an exhaust sensor & computer to adjust the carb. This carb replacement system reminds me of that idea. Hopefully, the RetroTek will be better than the "feedback carb" was... although it would be hard to be worse!!
