New dyno and pics of plugs

I don't pull too much timing. Maybe 2 to 3 in the mid-range. I have always run 100 octane when racing. When on the street I only ran 8psi, so there was no need to back timing off. (In MY car, EVERY CAR is DIFFERENT)

You got that right, I started on my first MSP and had to pull 6 degree's out and he's only running 7psi!!! Heard it pretty good at first, 3 degree's didn't do much, then with 5 it went away until it got real hot. 6 seems to be the key with his car.

When you dyno, why do you go to 6k? Don't risk it man, play it safe and got to 5500. I have about 20 or so pulls and they all look the same up top, it either levels off around there or drops off.

At 10psi? That may be a bit much, but no too extreme. Try to start out by just lowering the 1x8 and see how she does. You'll be surprised at how little a difference a few more degree's makes.
