    The technology behind the Big Gun TFI is that it functions like a carburetor. It takes the knowledge & experience that many of us have & converts it to a fuel injection interface. The TFI interface makes it easy to tune for different modifications. The TFI is to be used on EFI ATVs, UTVs & dirtbikes that have performance enhancements which require more fuel to run correctly; such as pipes, heads & even big bore kits. With its patented technology, this box does not default computers or trip engine lights. The TFI uses load based technology to monitor the demand on your motor and provide a fuel solution to reach optimum performance. This unit plugs directly into your factory wiring harness for easy installation.
