I re-ran the race with my newly purchased 1969 Camaro Z28, but this time I ran the car at 525PP, which is what Bowtie-Muscle's
tune actually called for. I removed the Supercharger. The car actually drove a LOT nicer...easier. I was thrilled with how well it drove at 550PP, but there were some moments where I definitely had too much power for my own good. Particularly coming over the humps Turn 6 to Turn 7. With the 550PP Supercharger, I would be just shifting into 4th gear and the back end would get very squirrely. It led me to short-shifting into 4th a few times just for stability sake. Well, with the 525PP properly tuned version I could keep my foot to the floor. 100+ less ft/lb's of torque will sometimes accommodate you like that.
Now, I'm off to purchase some more American Muscle and see how I can do running stock setups (I'll probably throw on SS tires for at least the first race, just to see how I hold up.
Then I'll go 100% stock, tires included).
EDIT: I just took my Challenger R/T '70 out for a spin and that dirty Ford GT40 tried to pit maneuver me TWICE!
Unfortunately for him, my catlike reflexes saved my car from rolling around in the sand and I managed the victory by a few seconds. What a scumbag that driver is.
