I will also add... Don't spill that shit on ANYTHING! I can see why it turns yours plugs orange. Last time I put some in (hardly ever) I pulled the funnel out and somehow I got little droplets on the side of the car below the gas tank. I walked into the house to get a towel and before I even got back it was dried on the car and was dark black. It came off with no problem but I'm glad I noticed it!

yup. Right on the bottle too :) Didnā€™t have a way to measure so I just dumped it all in.
from your description sounds like you were just under 100 octane

It sounds like the additional octane was helpful. Even when naturally aspirated, my car would be 3-4 tenths slower in 95 degree temps or DA over 3000. To me, 420's 11 @ 129 in those conditions is very impressive, especially since the Roush is prone to poor performance in heat.

I don't know how much of a factor the octane was but I think Roush's latest calibration does a good job of managing heat in spite of the kit's design.

Minding my own business tonight and enjoying the day. See in rear view mirror black 21 vette coming up hard behind me. Pulls up next to me and I'm trying really hard to ignore him. He's making a general PIA of himself so I go down to 4th gear and rolled into the throttle.

I was embarrassed for him. About 4 car lengths when I backed off. Pull up at the next light and I asked him would he like to try it again :) No response
