Re: Acceleration problem

Not sure what year your truck is or if you have a factory tach, but here's the easiest way to add the resistor to a 67-72 factory tach. Just ignore the fact I don't have a printed circuit, but just put the resistor between the two terminals. You'll also have to change the tach resolution from 6 to 3 in the tune for it to be accurate.
