Can't get right-S-AFCII settings

[iamtall77]

Okay, i've tried everything to get my car to pull hard or at least not knock since I got these 550cc injectors. I put a 2G MAF in at the same time and nothing seems to be working. I've tried different throttle points on the S-AFCII, tried to lean it way out, run super rich, nothing is working. I'm running at about +9 from 4000rpms up and only running 14-16psi on the 14b. I have a 2½" downpipe back with a cat and UICP. (other supporting mods) No boost leaks i know of and boost creep doesn't always happen, but I still knock (15+ counts) when I hold 16psi. My timing doesn't look that bad 15 deg or more, but it doesn't pull after about 4500 rpms. What % should I shoot for on the S-AFCII? Should I look for a problem somewhere else? The only thing i can think of is the 180lph fuel pump that I was told was in the car, isn't there. (the 180lph is from the 3kGT if you didn't know) Can i check this? (visible differences) Can anyone help me?

why? when he can do it himeself.

550s and a 2g maft are a good match. Put the settings to zero and try again.

Maybe reset the ECU at the same time.

I've reset the ecu numerous times, becuase it keeps reverting to the "bad" fuel trim mode. I know this cause my knock LED stays on all the time when it reverts. After resetting the ECU it works fine. I'm going to keep trying this, but I was wondering if anyone had some "basic" settings they use. With the 550's and the 2G MAS it should be close to 0 right? My lowest RPM (set at 800 right now) is like -9 and jumps to about +3 at 1600 or so. This is just the low throttle position as an example of how i have to get it to idle right. Ask me some questions so i can clarify what I'm doing wrong or where I should look. Thanks.

Yep. But you'll have to see what your fuel trims are doing, too, and make any necessary adjustments from that.
