Is now a good time to install my 550 injectors?

[CajunKenny]

Hey guys!

My fuel system is currently stock except for an Aremotive AFPR. I have a set of 550's, maft pro, and a walbro; but, they aren't installed yet.

I currently have the head off fixing a BHG.

So, my question is:

Will installing the 550's cause problems without the other items?

I would like to install the 550's now since I have the head off; but, don't know if there will be mixture or related issues...

(I will get a wideband and gauge, I just can't afford it right now.)

your supra will be running 25% richer....your cat could get clogged over a short period of time...its really not that hard to take the fuel rail off anyway. just wait until you a lex afm and then swap em.

pick up a lex afm and solve the rich condition with the 550's ( well, at least leaner then 550's and the stock afm)
i got one for sale for $50:naughty:

Hmm...with all my other goodies, I think I'll just wait and install them all together. Thanks for the offer though. If I end up changing my mind here in the next few weeks, I'll PM you for it.
