Our ENHANCED ECU (Electronic Control Unit) makes the car much nicer to drive whilst our SUPER ENHANCED ECU at uses more advanced techniques to provide the sharp response normally associated with multiple twin choke carburetters. Our LARGE THROTTLE CONVERSION provides an extra 25 b.h.p. comprising large bore throttles, supplementary cool air intakes, high efficiency filters and modified ECU. For those who want 6 litre performance from a 5.3 then our PLUS TORQUE CONVERSION is available comprising the Large Throttle Conversion added to modified inlet manifolds with internal ram stacks (photo right) to optimise resonance effects and boost mid-range torque.
