Will it work with the stock speed density computer? My injectors are going but I dont want to replace it with the 19's since I will be supercharging it soon. Do I have any other options?
It doesn't really matter so long as they're the same and the right style. The Ford pieces will be just fine. A word of caution though:
The 24s don't always perform well with SD. I run them as do many many others. Seem like one out of 5 stock SD computers has a problem with swapping only the injectors. Your Sig doesn't mention any mods that suggest you need 24s. If you're installing them in preparation for the KB install then you're on the right track. Keep in mind however, that the FMU that came with the kit is going to cuuse you to run rich in combination with those injectors and just about any high volume fuel pump. More than likely you'll end up having to swap the FMU disk to change the ratio to get it back in line --or-- you can run the stock fuel pump and the Kenne Bell Boost-a-pump. If you've not already purchased a wide band 02 for this whole deal then I will expect to see you post threads about blowns gaskets and/or motor in the very near future. The only alternative is a custom tune and even THAT, I don't consider to be a replacement for a wide band.

I appreciate the great advice!! Something I didnt know about!!! Maybe I should hold off on the KB since I dont want to go through the hassle again to check all of my gaskets. Guess I need to do a little more research or switch to mass air....
