The physical process of the building the 3.0L hybrid in the SVT seems to be relatively straight forward. However, the hardware to change certain control parameters like injector pulse width, etc. is a gray area for me. I logged onto Tweecer and Greddy and I couldn't tell what product to use or any idea of how to use in it in recalibrating the controls for power and driveability. More info and explaination if you would please.
