its really hard to say. maybe a video would help. theres so many things that it could be, but because timing is controlled electrically, i would sway towards it being an electrical issue.

it definately sounds a bit clanky to me. you're not offering a ton of information, but based on what i have i would pull the valve cover and check it out. maybe have a a friend start it and let it run for a couple seconds with the vc off if you dont mind a little oil squirting.
but.. how did you perorm the sai delete? i need details on this. one wrong move could be your issue

I havent done the full delete just yet the sai is just unplugged at the moment, everything still connected, i have cleaned throttle body, cleaned iat and maf sensors, done the throttle body adaptation, going to try plugs tonight, if i have time i will run with valve cover off and send you a video, would a bad second o2 be the cause?, i ordered the timing chain tensioner without thinking, and might return, only if its a mechanical part, audi doesnt return electrical aha
