550's without SAFC?

[1glaserturbo]

I'm considering getting 550 cc Injectors as we speak. My problem though is what would I have to get for some sort of fuel regulator if any? All of my current mods are listed in my profile, so that isn't a problem.

You need a S-AFC2 or DSMLink .

he might be able to pull it off with a 2g mas, ive seen it done.

You don't need the injectors right now, keep the 450s in there until you're ready.

Just because it has been done doesn't mean it's a good idea, I have also ran my car with just 3 cylinders just fine. 2G mas flows up to 33% more air than 1G maf and the 550s flows only 18% more fuel than stock 450s, not exactly close.

If you get a 2g mas and 550s you will be good. That's what i've got in my car and it runs great. A little lean under normal driving but i just get better gas mileage. You will also need a fuel pump though. A walbro 190 will work just fine and you won't need an AFPR with that pump. I'm speaking from experience here not just stuff i've heard. I would go 2g mas and 550s and then if you want to take it farther go with an AFC to get it really tuned.

Show us a log which shows that it runs great. Just because you don't feel a problem doesn't mean it's not there.

There is no way to tune a 2G MAF with 550cc's without a S-AFC or DSMLink. The car may run, but it's not running right. Regardless of how long you've been running it like this. This is not the correct way to do it. Do it right or don't do it at all.

like people have been saying, wait til you have a way to control the extra fuel flow... don't rely on O2 fuel trim compensation (which would be useless at WOT anyway) so you'd run rich which you don't want...

I want to see that log to
I just did the whole safc, 2g mas and 550cc comb. At idle the car runs rich as hell. You can see and smell gas coming from the muffler. Since I dont have a logger yet(its coming soon guys) the car doesnt get start up at all
