Has anyone used or have any knowledge of after market fuel injection systems. I am looking at CB performance and Type IV. Systems appear to be the same. They are supposed to work with many of the stock components. Both have a replacement for the stock system with a new programable computer for better performance.

The most commonly used on 914s are SDS and Megasquirt. SDS is favored by most. Megasquirt requires soldering and assembly.

The CB system is designed for the TI engine, it just happens to fit the TIV engine.

It's like buying a Ford part from a GM dealership. I drive our system everyday and have it in all but onne of my personal vehicles.

What about the new CB system that is fully programmable??
