I'm having trouble with my 42lb injectors maxing out at high rpm and under boost, I have a 255 in the tank and a propump inline and a boost sensitive regulator, I have raised the fuel pressure to 58 with vac off and the injectors are still maxing out. It is a 302 shortblock and the rest is in my sig, Are my rails and lines too small or what's going on? I thought the stock rails could handle this type of setup?
