Well guys and gals, I finally got my unit running :)

My AAC valve doesn't seem to be working, but my tuner found a way to tune around that and have a good idle.

But there seems to be a weird noise when I accelerate, sounds kind of like a misfire. I turned off each coil on my AEM, and it caused a different idle. And did the same for the injectors. Same thing.

The exhaust kind of sounds like machine gun fire (closest thing I can compare it to haha) when I accelerate.

Are there any ideas that the pros could throw out there that I could check? I'll try and post a video tomorrow.

Thanks

check the coil packs for carbon tracking, and make sure the plug gap is in check ( i run mine around .028)

no carbon tracking in the coil boots or plugs. my #1 plug is BLACK, checked the coil pack, and there is a small crack in it. so i have to replace that one.

here is a pic of the plug

all other plugs look fine.
i think that would be my problem.
