X2!

I've done several differant EFI systems without VSS and some were a lot of tuning work! Then add VSS and they all ran better, even if you don't need accurate speed, just the ECM/PCM knowing the vehicle is moving or not makes Idle so much better. Amongst other things!

Also done a lot of differant motors with TBI injection and made a small cap EFI distributor for every one. Jeep, Ford, Chrysler, etc...
