did you verify all of the timing marks? i just read back over your thread and noticed that you never stated that you rechecked. you can also degree in your camshafts if you are concered that they might be out.
i have no idea what's going on here.......S1's are in a buddys car and under full boost we have it spiking 29 and tapering down to around 25lbs with no knock at all on 93 octane. Car runs great down low, but seems to lose power up top. 12.3 at 112 was the best run. Sounds like some tuning needs to be done :shrug:

I was getting knock in the low rpm ranges with a modded rom so i've switched back to my origional one. Now I'm finding the timing is starting to come back alive and everything
I still got some knock at really low load, no boost, and rpm The car definitely pulls a lot harder up top you can feel it and i think with some tweaking on the tune I can get back the slam you in your seat feel with a little boost and timing.
I have the car running slightly rich right now at WOT holding a steady 10.8 AFR on our crappy as hell 91 octane. The low end power is definitely starting to come back as i play around with the tune just slow progress since its all on my own time

Same problem i had i think the tephra patch has some kind of tip in and let off bug where it goes a little lean causing the knock. Once i was back on my old rom the issue went away for me
