LB7: lb7 fpr mod

[Robby Avery]

Thanks ironmax that's what i needed to hear I save up for a new one I really want to swap a LBZ cp3 into her lb7 but funding want allow that as we speak maybe in the near future I will but for now I'll probably just replace it with a lb7 fpr and leave it alone til time and money allows for a LBZ cp3 ::thumb:

OK guys I just read this whole thing from start to finish and I'm confused. I'm doing headgaskets and injectors on my 03 LB7 on about 3 weeks and I have the lopey surgy idle so I went ahead and ordered a lbz fpr to install in my cp3 while it's all apart because from what I've read that will allow the tuner to command more fuel. Correct me if I'm wrong on that point. Now what is this mod about drilling holes in the pump and slotting the triangle shape in the piston on the fpr??? I have no hands on experience with these parts yet but I want to do as much as I can while I have it all apart to get the most out of my truck which is my daily driver/weekend toy.

Just install the lbz fpr and bend the appropriate fuel line to make it fit then get retuned to eliminate the lopey idle.done

Old thread I know, I read it but what's it the point of modifying the reg, wouldn't a new one be the fix? Was on mine.

Lopey idle replace regulator or use some 2 stroke oil, want more fuel delivery mod the regulator and suction pump.

Any idea if the regulator on sportsman pump or super sports from s&s is already modified?
