I hear ya... I figured I was getting too ambitious with the 3.3.. Timing tables are currently stock. I had my best luck on E85 with stock timing tables in the past, and since I planned on going E85 again with these 60# injectors, I haven't touched the timing tables yet.

However though, still don't know why I would get that KR under no boost to very little boost, and not at higher boost/RPM/throttle positions in lower gears pulling much harder...
