Default 13:1, 150 hit and pump gas

408 LSX

13:1 Compression

26* Timing

150 Hit

BR7EF's @ .028 gap

91 Octane Pump gas

I'm running the MSD 6010 and have the motor on 30* timing and pull 4* for the 150 hit. No wideband in the car, street tuned.

That sounds like a disaster in any other case but here doesn't look like it turned out too bad

That plug looks like it has some miles on it. To read the plug, it should be a one pass then immediately killed and pulled. That is the only way to get a good read.

Here is a one pass plug out of my car. See how clean the porcelain is with just a light fuel shadow. Even as clean as it is, my car is still a little rich.

Also, see the clearly defined timing mark on the electrode? Mine might like 1 or 2 degrees more timing next time out.

you can't drive on them. Install them in the staging lanes, do your burnout, make a pass and shut down on the return road and swap them for another set. Then you can read them.
