Fuel Injection Recommendations

I picked up my fitech when they were relatively new. (2015 or 2016) I had to buy a carb and for near the same price i could go fuel injection.
I did have a few issues with the external fuel pump so i made a tank for an aeromotive stealth internal pump.
Later the 02 sensor messed up so a stock vw sensor went in.
I just ran new ptfe fuel lines from tank to engine bay to replace the pushloc because i was getting worried about them.
I do have a slight issue with the hand held, but it does what its needed.

The only reason i am considering holley stealth for the next unit is mainly because of the name and possible connection to digital gauges on the dash. Just the metric speedometer is holding slowing me down. Also dont have the 400 stroker built yet.
