i have an 89 vert: with shorty's , x-pipe, 65mm mass air meter, 250lbs fuel pump, and a powerdyne 9lbs kit. my timming is at 8 degress tdc and im experiencing a backfire when i down shift. Also the car puffs a little black smoke when i shift hard, i think im running a little rich. I would like any valuable feedback.
I will be putting on an adjustable fuel pressure regulater in the spring, as well as injectors(what injectors do i need and what should my ruel pressure be set at?) Thanx
