Auxiliary Fuel (Port injection) Tuning

Auxiliary Fuel (Port injection) Tuning

$ 225.00

This is for customers running additional port injection. Either injection via throttle body, or injection via intake manifold (port). The fact that this requires tuning of two systems, and the complexity of these systems, is why isn't included in the price of an E-tune. Please see below for a list of HP limits for the factory fuel systems, and at what point you will need to upgrade to an auxiliary fuel system for standard fuel. E85 requires Aux fuel injection for ANY vehicle. 
Ecoboost Mustang - 400whp
