I have a first gen and need to wire in a 2nd set of injectors. Do I wire them into the two injectors all ready there or will a fuel controller allow this? Also, how does a fuel cut defender work?

 

You have to have some form of control for them. You can't just wire them in along with you stock injectors and expect them to work good. If you have an additional injector controller you could add them in but I would recommend a standalone type of ecu.

A fuel cut defender is only needed on the 2nd generation Turbo II. The ecu cuts fuel to the engine above a certain boost level. The fuel cut defender fools the ecu into thinking that there is less boost so this doesn't happen and so higher boost can be used.
