I have an intake and full exhaust on my S4. I re-wired a Walbro, also. It's running way rich, so I was told to get a FPR. I have an SAFC II, but, even after trying to tune it down, it's still WAY rich. If i getb the Aeromotive FPR, what else would I have to get/do to put it on? Also, would too much fuel cause my car to stumble when the secondaries come online?

What are the injectors your running? I find it hard to believe the SAFCII cant turn them down.

JoeHawk

I'm just running the stock injectors right now. I had it turned down to about 22%, and it still read rich on the a/f gauge(I know, not accurate, but a good idea, nonetheless) So, I don't know what to do. I'm kinda lost.

You're running an N/A, right? With a Walbro? Why?

I've got full open exhaust & intake also, and run fine A/F ratios with the stock pump...

Sorry, I haven't changed my profile, I did a Jspec swap.

Ahh, make much more sense now

If it's turbo...

Do you have any idea what your rail pressures are?

JoeHawk

I have not a clue. It sucks not being too informed on the stats of my car.
