There seem to be so many claims by different companies I guess a person would be better off going from references by other users than accpeting claims by the manufacturer. I am using the FAST system on my 61 corvette and should have this running by end of summer. The programing and tuning method seems to be close the the Accell unit. If there is such a thing as simplicity when it comes to fuel injection I would think that system would be the leader in fuel injection technolgy. Where did you make the purchace of your Carabine system from ?
