I ordered a set of new bosch 3 22lb injectors from FIC for my 90 corvette. I received these today and they don't look like the new bosch 3 design.

 

Your right , not bosch 3's. They look like Lucas. You should have gone with the thirdgen vendor southbay

 

Those look like ones I just installed in one of my Corvettes, replacing the Multec injectors.

Jon @ FIC said the new design (like you have) is more tolerable to alcohol in fuels today. I believe they are made by Delphi. Call him and ask, but my car runs AWESOME with the Delphi injectors vs. the old Multecs from Rochester.

 

I talked to Jon and he said these are the new stainless steel Delphi's. Direct replacement and have a 5 year warranty. Im gonna give them a try

 

I do not have a fmu, the Paxton kit did not have one.

im running around 6 psi boost and used tunercat to modify the prom slightly for fueling.

being about 18 years ago and many laptops since I really have no idea where it sits but as I remember it ran pretty good with no codes.

I just figured that after this many years sitting in my garage it is likely the injectors are gummed up and at a minimum need a good cleaning.

but if there are better injectors now why not just swap them out to avoid any issued

 

What is the part number on the injector?. Just an FYI....most injectors are all fuel compatible and have stainless internals. Yes if injectors sit they are more likely to gum up....has nothing to do with the tolerance of the fuel. Old stock multecs in our opinion should be swapped out with newer injectors....they will eventually fail at some point or another. Keep us posted
