Default Fuel Lab 42402 or Magnafuel 4301 for big boost

Need to get my fuel system together for turbo build.
410ci in a CTS-V w/ big snail.

I know the fuel lab is "speed adjustable" and is digital, but not sure I will realize those benefits in my setup. Build is primarily for the street and running at standing mile events.

Will be matched to appropriate rails and a boost referenced regulator with a return.

Which fuel pump would you run and why?

I saw the Fuel Lab pumps at PRI last year and it's a really good story but I've heard of more unhappy than happy customers. Our crew all run MagnaFuel. That's not to say that we haven't had our problems. One of LS2Formula's magnafuels was dead on arrival and I burned one up in a year of street driving. In all fairness, I did run it dry a couple of times due to the bulkhead fitting in my old tank with no sump. Both times, their customer service was excellent which counts for a lot.

If I didn't already have my 2025 Weldon I would have gone MagnaFuel.

Why not just go straight to the 4303 pump?
