I spent some time on the 5000-6000rpm range this afternoon... 5th gear should pull harder next time if it doesn't knock.

The ~2 gallons of c16 was not needed, I think. I added it halfway thru the day to see if the 1-counts of knock would go away. As I thought it's just engine noise. I changed the meth/water mix from 50/50 to 80/20 and it made a nice difference. With a big nozzle 50/50 is too much water.

I would expect this much boost to hit around 120. On straight c16 with a little more timing, leaner afrs, and 32-33psi it should trap 130ish so I think I am on track.
