Default Too much fuel for a NA setup??

At the moment Ive got two walbro pumps, upgraded stainless fuel lines, aftermarket fuel rails and 42# injectors supplying fuel to my 4.6 equipped with a blower.

If I were to ditch the blower and run the engine NA, would I need to downsize all this stuff or can I keep it all installed and have my tuner adjust my tune appropriately.? Thanks guys.

your tuner would have to cut it way back, the 42's may still be too big, but I'm not sure. I hope that pump you have is a returnless pump, I know a while back walbro had issues because they weren't returnless.

Why do you have a dual pump setup with only 42 lb/hr injectors?

I don't think this is going to work, the stock pump is good for almost all N/A applications, and a SVT focus single setup would make do for even the most wild n/a setup (with no nitrous).

Interested in a trade for your dual pump setup? If you are, I would probably be interested in either a trade or buying it outright... I have plans this winter

What injectors are stock for the '01 4.6 engines? I can use them and delete a pump keeping the same lines and rails. At that point I should just need new plugs and a tune and I'd be ready to roll. I don't think I can get rid of this two pump set up completely, I don't have the time or resources for such a job. Any suggestions are welcomed in regards to my situation.

why are you pulling the blower? Whats your setup going to be n/a wise?

your fine on the stock injectors until you start getting into the motor itself. once you do a shortblock/heads etc etc your going to need to upgrade the injectors to at least 24 lb/hr. I beileve the 19s cut out around 310ish whp?
