It needs to be tuned with a wideband. I recommend against it as your sole tuning option. Ditch it, get a real fuel controller and get it properly tuned.

You can NOT use the Lex AFM housing with stock injectors. See the FAQ about it please: http://www.toyota-supra.info/forums/...lexus-afm.html

So if I get a wideband or some other means to tuning, do I still need to get 550 injectors. Or can the stock ones? Will they allow enough fuel in?

You still need some means of supplying 25% MORE fuel. I thought I covered that in that FAQ thread... I guess I'll have to go back over it.

ok. *cracks fingers*
Basically..
you're talking about two different beasts.. piggy back and stand alone.
stand alone = complete hardware upgrades like the lex honeycomb housing and injectors.. piggyback would be electronic tuning such as installing the honeycomb then adjusting using a wideband and a safc or something else.

adjusting that screw is not a method of fine tuning.. saying your checking your afr by how your engine responses and if you have a check engine light. Could possible be causing untold damage to your engine. My suggestion is to STOP. Do it right or your looking at an expensive repair. like a new engine due to detonation. These are not opinions..

I have only started the engine to see if it has gotten any better. Other than that, it's been sitting in the driveway. I have a shitty auto meter air/fuel gauge and it says I'm in the green. I'm gonna get the 550's and a piggy back system and scrap the a/f gauge and get a wideband. Just wondering if there is a preferred piggy back to use, or are they all pretty much the same?

wide band is the way to go.. couple different brands on the market.
