What is the difference between complete supercharger kits and tuner kits?
Tuner kits are designed for qualified tuners or race shops that do not require the fuel management systems most often included in complete or standard supercharger kits. Among the items most often excluded from these kits are fuel pumps, fuel injectors, FMU, air-inlet assemblies and ECM programmers or timing controllers. Complete systems usually include all components required for a bolt-on installation by an experienced do-it-yourselfer.
A good rule is if you are not sure what the difference is between tuner kits and complete supercharger systems, you will need the complete kit. If you are a racer who already has an upgraded fuel system or plans to do their own engine tuning and timing with the addition of a fuel delivery system then a tuning kit may be the ticket to horsepower you’ve been looking for.
