Where you might want a couple maps is for different grades of fuel. I have one for 93/4 octane and one for 91 octane.

Would this not make your car run rich when boosting at a lower pressure? If it were tuned at 11 psi and you drove it at 7psi? I was always under the assumption that you would need 2 separate maps for a situation such as that.
