I have the mods in my sig, 355, s/c, intercooled,.etc. I am working on a deal for some 30lb and 42 lb injectors.. i currently run Bosch 26lb, custom injectors. They are very good and cost me like $700-800 new. Anyway, I may sell them, and upgrade. What size should i be running,.. is 26lb enough? or should i get the 30 or 42lb? the new ones are ford injectors,.. and not as *** as the bosch i have. I have a FMU set at 24lb. please advise. thanks

 

the real question is: "is it running out of fuel? at the top end at WOT?"

 

well, with the old setup, which is essentially the same, (or a little diffenernt), the fuel pressure and volume was staying up, and the 02's were good,. So I guess not. Good point thanks, I guess i don't need them. thanks
