As I see the addition of the Walbro 225 fuel pump as a common theme of the F/I family, would there be any advantage to using it on a modded N/A engine? I was wondering if my Crawford + Borla exhaust might need some extra fuel in the upper rpms. Plus, I plan on squeezing ( 75 hp shot ) later this month & certainly don't want to starve the VQ. Let's have some opinions, gang!

I don't think you will need one.
For nos, I think the only way you can tell is if you have an air fuel controller and see if your knocking or not via a dyno. That's the safest bet.
