i've been thinking of using one of those laptop chips with the 5.0 injection on my car..... but i'm still thinking of maybe custom building my very own SFI setup.... i have an airgap manifold laying around that i might try drilling for injectors, and then build some fuel rails, and a throttle body for the TPS and MAP sensors... then i just gotta do the basic crank and cam trigger stuff.... only problem is that i would need to make the timing independant of my distributor, or make a coil on plug to go along with the SFI
