If it idles fine, and runs "fairly well" under light throttle, and you have the rockers adjusted properly, then I'd bet on you either have plug wires crossed, not clipped into the opti well, or even a burnt wire. Crossed wires is so easy and so common. Check them very closely!

I set the 918's set at 180 install height, and at 1/4 turn past 0 lash.

I'd also suggest you check for a vacuum leak and check the injectors are properly wired - didn't swap connections. Also check the wire to the knock sensor itself. I had a burnt wire that was arcing to the knock sensor and the car had fits as soon as it went into closed loop!

Scan the car while driving and post the file, or send it to me and I'll look at it.
