Description

This kit converts carburetors to electronic fuel injection, resolving cold start, hesitation, vapor lock, and flooding issues. It's a cost-effective upgrade with simple installation (four wiring connections). The system features a self-tuning ECU and a 3.5-inch full-color touchscreen for setup and tuning, no laptop needed. It supports up to 350 HP naturally aspirated and 285 HP with forced induction, using two 100lb/hr injectors. The master kit includes a complete fuel system: 20ft of 3/8" vapor guard fuel hose, fuel pump, filters, and all necessary return fuel hardware. Also included are a Bosch LSU 4.9 Wideband Oxygen Sensor, OEM style TPS/IAC, internal fuel pressure regulator (preset to 58.5 PSI), stainless steel T-bolt clamps, and a weldable stainless steel oxygen sensor flange. It's compatible with C4/C6 Ford, TH350, 400, and 700R4 transmission kickdown levers, and accepts common 5 1/8" OEM or aftermarket air cleaner assemblies.
