The
Powerjection III is an amazing
accomplishment in engineering. It is
by far the simplest and cleanest
aftermarket EFI system available.
Which also means it is the easiest
to install and tune. The “Adaptive
Learning” feature eliminates the
necessity for laptop programming and
tuning, except on the most radical
engines. |
