Q:  What is CPI? 

A:  Charge Pipe Injection (CPI) is our new proprietary system that allows you to add additional injectors to your boosted application with any standard 1/8" NPT female connection in your charge pipe or intake system.  It's commonly referred to as "the 5th, 7th, or 9th injector". 

Q:  I have your port injection kit and would like to run a 7th injector in the charge pipe, what fittings do I need?

A:  You can use the -6an to -4an flare adapter to connect the fuel line to our rail and then run it straight to the injector.

Q:  I'm already running a port injection controller, how do I connect the new injector to run off that?

A:  The easiest way is to get the wiring harness with the PosiTaps and connect it to your existing harness, otherwise you'll need to splice it in.

Q:  I don't have currently have an injector controller, can I get one with a harness for my application?

A:  Yes, you can use one of the off the shelf controllers and harnesses if it meets your needs or order a custom harness from us.  Please allow 1 week for custom harnesses to ship.

Q:  What fuel sources can I use?

A:  You have multiple options for that.  You can connect to your stock fuel with our adapter if it's a 5/16" quick connect.  You can connect to the fuel rail, the 1/8" gauge port on your fuel regulator, your meth pump, etc.
