Is my problem ignition or fuel?
 

I just finished up my E6k flying lead install on my FD (I was previously running the k2rd adapter harness). Basically the only thing I’ve changed are the wires from the Haltech to the engine components.

I fired it up and everything sounds good, everything is now working, gauges and sensors are reading correctly, fans kick on when they are supposed to, etc.

However, when I take it for a quick spin, it lacks any sort of power, and above 2k rpms I hear this really weird oscillating sound from the exhaust.

At first I thought it was ignition, so I changed all 4 plugs and verified that they were firing. I don't think the timing could be off just by changing the wires, but I hooked up a timing light to L1 and I’m reading the main tooth at about 10 o'clock (I'm a timing light noob, but I’m guessing that 12 o'clock would be 0 degrees or TDC? so I'm reading ~35 BTDC?). I couldn't get a pick up off the trailing wires, but I did make sure they were each hooked up to the correct DIG OUT ½ of the Haltech. So, I’m confused on how ignition could be causing my problem so my thoughts turn to fuel.

Unfortunately, I don't have a wideband, but one is on the way and should be here this week. But could fuel cause an oscillating noise in the exhaust? Maybe the secondaries aren't coming online? I think I may need to wait for my wideband to read the AFRs before I will be able to tell.



Any help is appreciated.

Just for people who are searching later on, the trailing coils were switched. I went off the K2RD diagrams that i found on here and they were wrong. I found someone elses explanation of it and they were correct. It fired up sounded better and drove just like it used it.
