surprisingly I've searched and can't find anything on this. So as questions go, 1. Are they worth it, 2. Are 5.0 injectors compatible since nobody makes big ones for 3.8, and 3. *What is the stock* rate for these? I think its 15lbs but not sure. I read about them being no good for the CFI but since mines direct injected and I plan on using one of Morana's ported intakes I thought it might be worth it. Thx everybody.
