Do I need a fuel pump to spray 150? I have a new stock fuel pump in my car. The car runs 12.6:1 afr @wot. I have a harris speed works 78mm plate on it. I'm either gonna buy a fuel pump or a timing controller for the kit. I can use efi live to retard the timing if I don't have the controller but I would have to change it all the time. So can the stock fuel pump flow enough to keep up with 150 without leaning out the afr?

I would not feel comfortable spraying a 150 on the stock fuel pump especially with a lot of mods. If you are close to stock, you could probably get away with it.
