I've got a few cars running 96lbers on stock computers.Not much problem with idles holding 14.5-1 A/F.Fuel pressure is ussually 45psi with boost reference only.Big difference is minimum injector pulse and the driver box.

Thats a good point!

Ninetres, what driver box are you using?

It all depends on your motor and the minimum pulse width you can get away with on the injectors before they start to not open which is why it is different for all the combinations. A lot of the time it will run rich down low with big injectors and smaller motors because you are riding the minimum pulsewidth of the injectors at idle. If you try to lower it too much it just won't open and instead of a rich condition you get stumbling so it's a balancing act. You can lower the fuel pressure to compensate a bit but sometimes you are just at that limit of the injector. Many bigger low impedance injectors with a driver box run better than a sloppy high impedance large injector at small pulsewidths for sure.

I believe it is a Versa Fueler. I got it and the 96ers from Nasty Nate.

I've used the Versa Fueler and AEM driver box with 96lbers. 43psi on one and 60psi base on the other. Both 1:1 boost ref and using the stock PCM. 14.7-15.0:1 no problem. Getting the PW down is key. GL, I'm sure it is something stupid.
