I may be wrong on some of this stuff. Im not sure what size injectors the roe, heffner, and DLM kits use, but I know they all use Bosch or Ford Motorsport injectors. I beleive DLM supplements most of his fuel through 4 injectors mounted in front of the TB's. Heffner and and some of the TT guys replace the stock internal fuel rails in the intake manifold with a new rails and a return system.They also use a new aftermarket pump. Some use retard boxes and It hink the are a good idea to stop detonation that may occur with weather changes. Im not sure what computers they use. This seems to be a "hush hush" discussion but I have heard good things about many of the custom tuned tuner boxes, and the new to the market VEC2.
