AFC Tuning for Bigger Injectors REALLY need help!

[nevermore]

ok I have 2 bad injectors in my car I have a 2gnt port and polish, CAI, upgraded exhaust and stuff like that... But I want to get more fuel in because my injectors are dead. I have a turbo fuel pump in now, and I want to toss in some 450cc's that my buddy has laying around I figure there free and I know how to install everything including wiring... but I don't know what to set my S-AFC II settings to... someone told me -25% but I wanna make sure... is there a way to figure it out? Let me know. BTW I do not have turbo yet. So if that helps for the -/+% I need... thanks

first, i dont know what a 2gnt port and polish is, can you inform us of that?

second, i would recommend not putting the 450's in. it just wont run good or right. go to a junkyard and try and find 2 stock injectors to replace your bad ones with, and then hold on to those 450's for if or when you ever go turbo. the stock ones arnt even maxed out yet with those mods, so bigger ones would be futile.

A PORT AND POLISH... what does it normally consist of? TB, Intake Mani, and Head? Normally.

ive never seen packages like that. you can get you TB bored out, and your intake manifold ported and polished and your head ported and polished, but they dont all have to be bought at once. and head porting and polishing can get extremely expensive, like $450+... wait why am i talking about that? you dont need that big of injectors unless your boosting, you wouldnt even need them if you had a decked out head, and ported intake mani and whatever else, you wont be pushing enough air NA to need them that big.
