I dont know how the jackson works.But i have a msd BTM it retards the timing as you build boost to decreas chance of detenation.The msd has a knob that you mount in the car to adjust how much you want to take out.If you want it ill sell it for $70 shipped.
Huh i will probably buy Jackson Racing one cuz it will work better with Jackson Racing supercharger. I think it will.
This thing is just for controling how much PCI I want for supercharger to deliver?
And all you doing is just choosing how much u want? (what about AIR-GAS ratio is it automaticly changes when you changing PCI?)
