First off let me give the details.Stock SRT28 at 13lbsZ32 MAFWalbro 255 Fuel PumpSAFC IIBrand new NGK BKR6EIX11's.

I got on the dyno this weekend to tune my car. I've been waiting for this for some time now. I do a pull in 3rd, and the car leans out real quick at WOT. After adjusting the SAFC I do another pull. It still does the same thing. It's running like 13.5's 14.0's. After that I hooked up my fuel pump to a constant 12v to see if that will help. Still does the same thing. I'm wondering if maybe I need a FPR because my fuel pressure isn't high enough. I'm going to check my MAF, and SAFC wiring tomorow. Any input is greatly appreciated.

I had the sensor settings at 2 in 2 out. Could this be the problem instead of running 2 in 5 out?

Would not running these settings make my car run lean even after adjusting the SAFC?

are you still running stock 370cc injectors?? If so, thats your problem...getting a fuel pressure regulator may help, but you need to get bigger injectors... you are probably at the stocks capacity...just my 2 cents

2in 6out is the correct setting. Anything else would throw off the reading. I'm running a z32 maf with safc neo.

Alright. I have changed my settings to 2 in 6 out. The car starts up perfect now. Before I would have to give it gas until it warmed up for it to idle correctly. I will put my car on the dyno this weekend and see what happens.

ok, sorry to pull the ignorant card but what exactly does that mean "2 in 6 out" I have about the same setup and my car seems to be running very lean and I also have to wait a while before it idles properly. I'm also running 550cc injectors with the safc. Thanks.
