Carburetor, MSD, Holley Sniper EFI questions

I had no experience with efi or Mopar ignition systems before I began my adventure. Now I have the Holley super sniper, hyper spark ignition, coil. Wiring them up was easy. I have the tanks inc tank and pump controlled by the efi. I have an internally regulated alternator . Having these pieces I was able to remove the ballast resistor, Mopar ignition box and voltage regulator. It was rather easy to do.
Kent it is easy if you can follow the instructions and put that into practice but some people find that part difficult to comprehend not having a dig at anyone. I’m on the Holley forum both on Holley and Fb , the fb one is pretty good and there’s a lot of good people helping guys out and I see people all the time complaining about this product is **** , I want a refund . There is some issues with the sniper where there has been ecu malfunctioning **** inline pumps not lasting ,**** connectors on the injectors coming loose and causing headaches for customers.when they are asked to run a data log so the people on board can get a better understanding on what’s happening the person having issues wouldn’t have the faintest idea , or just in engine perimeters what engine cu inch what ignition system etc they input wrong info or finding a 12v source as my screen keeps rebooting as I’m cranking ,basic things because people don’t take the time to read the information in front of them or not understanding it . It’s not as forgiving as a carburettor there a steps to be followed to achieve a result. You have to agree though these classics we drive were very basic and than 60 years later here we are integrating later tech Into them Weather to get better performance or fuel mileage so do your research have a plan of attack and just understand on what your dealing with.
