I have a 91 Firebird, TPI, 305 & am interested in getting an ATI Procharger system... I noticed the systesms they had were for the 5.7, but I spoke with them and said 9psi on a pretty much stock motor would be fine... Anyone else done this?

Later I plan to have rebuild the motor for a supercharger, etc...

For now, I know I will need bigger injectors 24lb as opposed to 19 the stock 305 has... and a chip upgrade....

Any help, notes or info from anyone else with this setup would be appreciated....

This board has been a great source of help and info... despite the 2 bad apples that took my money in the classified sections... hat's off to the members that are here to help one another...

Honestly If you need new injectors and a chip anyway, I would go with #42 lb injectors (No need then for the FMU), Convert your exsisting 7730 computer to 7749 (just a wire swap) and make a chip for that. There is plenty of info around on how to do it. This way the computer will control the fuel and timing instead of relying on a FMU.
