When a manufacturer offers a "complete" kit with EVERY single part necessary to complete a supercharger kit installation they have to make some assumptions about the customers car.   The first assumption they make is that the customers car is bone stock currently and that they have made no modifications to it already.   The second BIG assumption is they they are specifically going to offer the supercharger pulleys to make one boost pressure level, and their fuel / MAF / tune upgrades to make a new higher singular higher horsepower figure.

All of the Tork Tech supercharger kits are capable of a wide range of power, depending upon what pulleys and boost levels are used.  In most instances this range can be from 150  to 300+ horsepower.   In other words, our Terminator kits can make 400 RWHP on a stock engine with 9# of boost but they can also make 530 RWHP on a built engine with different pulleys making higher boost pressures.  Because of this we are not going to give our customers a specific fuel injector, or MAFS, or fuel pump, or even a detailed computer tune for the low range of a kits capability when they may have plans for the middle or high point of the kits capability.

Tork Tech recommends you purchase these commonly available items on your own from any of the hundreds of companies that offer injectors, MAFS, fuel pumps, and tuners to suite the power levels you have in mind.
