What cam would you run?
This may seem like a 180 from where I'm talking about heading, but I figured I might bounce it off of you guys since we're talking about cams...what about advancing the cam that's in there 4 degrees? I installed it per the cam card and, if I remember right, it came up at 107.5 ICL when I degreed it, so I left it alone. I'd have to dig through my notes to be sure though.
I've attached a screenshot of one of my LM-2 logs to show how the car currently runs. You can see after leaving the line at 2k, it hangs around 4300 to 4500 briefly, then takes off.
