Stock 460cc primaries. I've verified that the S-AFC settings are actually correct, it turned out that they got set up backwards, so -10% actually means I'm giving it more fuel.

I was meaning the basic configuration (5 in 5 out arrow up and to the right) and such. I'd definatly try to bypass it, and those injectors are fine for your car. If bypassing the SAFC does nothing, I really can't see it being a fuel or spark issue then.

I'm starting to believe more and more that it's the AFM, because I was having odd problems (before supercharging) that most people suggested was my AFM. I just think that now, because the AFM is getting worked a lot harder, the problem I had before is simply made worse.

What was happening before was that I had to fatten the car out on the top end a bit, otherwise it would do what it does now, but only above 5500rpm.

What does your SAFC say your AF % is when it's doing this? Is it reading 100% or something crazy? It's also possible that since you've only got a narrow band TPS that the Hi/Lo switchover is killing it. Hard to say at this moment.

Yeah, I'll get back to you tomorrow, which is when I'll check the timing and the MAF.
