at what point do i need to upgrade my injectors in my 91 auto talon?
i have a set of 450cc laying around and i know the auto come with smaller. can the stock auto ecu handle the 450cc? should i wait till i upgrade my turbo?

depends on what you actually have...your profile says you have an afc and 560cc and a bunch of stuff, so I don't know why you're asking about 450s...so I'm just going to assume that you're talking about a different car than the one you have in your profile. In that case, I would suggest waiting till you do the turbo and have a fuel controller, cause the ecu will read differently between an automatic and a manual, and if you throw in larger injectors, the duty cycles will be a bit screwed up, even if they are only a bit larger. Also, you wouldn't notice any power gains if you put in larger injectors like those. So just to be completely safe (cause ya know how often our stuff breaks down even when we DO play it 'safe'), I would say DON'T put the injectors in now. Good luck!
