I will never care what a “stock” car runs. 90% of us mod our cars in one way or another. Demon/Red Eye/ Hellcat/GT500 are all great machines. Run what ya brung and see what happens. If you lose to a modded car then admit the loss. If losing bothers you, mod your car and improve your driving skills and try again. If losing doesn’t bother you then you are lucky - because there always is going to be somebody faster.
I'm interested in what the new C8 owners are going to have to say about being able to mod that car after news came out that apparently it's going to be super expensive to just tune those things.
