hope you have a good retune on the ECM....ac 42 on the plugs, I would get the timing at full advance 26-28..but there is a lot of variables there...from what Ive seen the stock EFI may be a big issure with what you have....I'm running a M3 ona 509, just took off the EFI went to a carb...to much B/S with trying to get the ECM tunied right...some get it right...some don't...if you don't very bad things happen..
