I have a Fitech unit. Did lots of reading and research on both when I bought (in 2017?) Anyway, decided on the Fitech. I have it controlling the timing, went with a tanks in tank and new PTFE fuel line with AN fittings and two fuel filters. So far so good. Still lots to learn, as far as timing curve and tuning ,.but it fores right up, hot or cold.
Take your time and be sure your wiring is up to snuff. You'll need a good solid 12 volts in crank for the system to fire the injectors. Like MSD needs 12v in crank to fire.
