what fuel injector size should i use?
I have a 8psi dual intercooled 1995 LT1 camaro with stock engine. I have heard you can get rid of the FMU by adding 42# injectors. Is that a good idea? and what should my fuel press. be? What other mods should I do with my supercharger?

If you go to SVO aka Ford Motorsports 42# injectors you will need to tune your set up. I recommend LT1 editor and/or Tunercat, the editor is what I use and it works great. I haven't heard anything bad about Tunercat.
FWIW, I run my 42# SVO injectors at 49psi, vacuum disconnected, and in the LT1 editor I rate the injectors as 47.5#. Thing runs like stock, but is a bit rich and ugly on a cold start.
You will also need a session on the wide band dyno to fine tune your set up.
What other mods ?? Sub Frames and Headers ... in that order.
Hope this helps
