Reply to "Fuel Injection"

The problem that you are describing with your Holley EFI system sounds like a set up problem. The port injection aftermarket EFI systems have set up tables that have the ability to add or take out fuel at certain temperatures as well as advance or retard timing. If these tables are not set up correctly, then the engine is not going to run correctly. The Holley EFI should have a data logging feature which would help to determine what is going on with the system at any given time that the engine is running. My FAST XFI 2.05 system has a data logging feature and I have used it before. You do have to attach a lap top computer to the system to get the data that you want, which for myself was a bit intimidating the first time. Of course, since you have already switched back to a carb, then it is pointless to go back to the EFI system. Perhaps this bit of information will help others if they should decide to switch over to fuel injection. As I had stated on another post here, the best place to get an aftermarket fuel injection system worked on is at a shop that does conversions on muscle cars and other older vehicles that had a carb on them. Just because a shop has high end modern vehicles there does not always mean that they know how to tune a stand alone aftermarket fuel injection system.
