Having run hundreds of tests on the. effect of 2-valve throttle body upgrades on everything from stock to supercharged combinations. (both centrifugal and positive displacement), it is safe to say that throttle body upgrades on the 2-. valve motors are a worthwhile endeavor.
VDC may refer to: In technology: Virtual design and construction, modeling software and techniques to design and evaluate possible construction processes; Volts of direct current; Video display controller, a computer graphics chip; Vehicle Dynamics Control, a means of increasing vehicle stability through a combination of throttle restriction and braking
GDC is a frontend for the D programming language. By using GCC as a backend, it gives us the ability to target the same platforms that GCC targets. This project was originally started by David Friedman. His first announcement can be found here and his original project page can be found here.
