While adub3 just answered this, here's a very helpful PDF to keep for your records:

I don't know why, but Copp makes this extremely difficult to navigate to on their website (or at least it isn't where you expect it to be). I just google "Cobb N54 map notes."

Just go with a standard map that fits your cars mods or lack there of and the octane you run and you will feel a huge difference in power. I know I had a HUGE grin on my face the first time I in 0-60 in 4.5. Have also had some great races against larger v8 cars with waaaaay more power. Funny to see how big their eyes get when you pass them in a 6 banger.
