I'm rebuilding the 200 I6 in my '67 Falcon, and turbocharging it ( will have 8.3:1 static comp ratio ). it will be run blow through at 6-10 PSI with an intercooler. I would like to have Throttle body injection on it, for reliability, and the tunability factor, working with the Turbo and such. I know that even tho there is no kit to put EFI on a small Ford I6, it is possible, I can get thru the mechanicle end of the EFI, like a DSII distributor will give the VR signal the computer needs to tell cam position, and I know there are bolt on throttle bodies that bolt right on the integral head, such as 1's from ford Tempo's and early Escorts. also the electric in line high preassure fuel pump, with a boost refrenced regulator. but my question is, I need an aftermarket tunable brain box that will be able to cope with the Turbo, I'v heard people rave about Megasquirts and that seems like a viable option but I'm not great with electronics and these need to be put togther ( putting the main chip togther ), but I could pull it off, also heard about FAST XFI brain box's and these are supposto be great also, and a few other company's making brain box's like the XFI. what should I be looking for or asking for as far as tunability?
