Ya I dont the mph and rpm through the beams, is that the timming lazer beam? As I said I dont really know to much to new.

The first stage is for the first two gears to protect from over revs if you blow a shift, all so off the line I can set it for what ever rpm and keep my foot to the floor and your rpm will stay at what you set it to. Second stage is just to protect 3 and 4 from over revs. I beleive from what I have been told, I also think there is something to do with more spark also but not to sure about that.

What does the MSD digital 6a plus do for you also the hei distibutor that must just provide more spark I am thinking how did that work for you?

ANd yes I need tires but I have a spacer ring to match the crager hole patteren. I want to lose that so I need different rims to match the right bolt patteren with street slicks then I will have more traction.
