Injector Question

[dthquazi1]

i am putting on my 16g soon and i am worried about it getting lean during boost. I dont have a walbro (dont know why) but i have the rewire on my stock one. I noice something when i was doing my fuel rail. Two of my injectors have blue tops and two have black tops. Why.. Also should i be safe running 16lbs of boost on this setup...more?

i dont know all i know is i got two blue and two black. are the numbers easy to find. i dont wanna hassle with pulling the whole rail to get the numbers again(i have done it so many times)
