We ran at 29* for 8 hits. Then we dropped to 28* and picked up another 1 mph. There were still a couple of plugs that were on the edge with that tune up. We have the Grid installed in the car so we are going to install then ICT fiber optic this winter so we can take out .5 to 1 more degree out of a couple of those cylinders. That "baby shot" put the car on the bumper twice at Norwalk this year. Needless to say we didn't jet up that weekend. We needed to get the suspension under control. We ran 145 mph lifting twice on the last run at 28*. That's with the 150 shot.
What fuel are you running with that 300 shot p4msi1? If it were me I'd be using C23. We are using C12 for the 150 shot.
