I never gained any mph by taking out the headlight....

Air intake is RIGHT behind the passenger headlight. Pulling it gives a cooler charge and if you wall off that area it can provide some pressure to the intake too.

I don't think it would ever help here in Phoenix unless your were racing in the months of Nov-March.......Although I'll still attempt it.....

I typical gain 1psi and 1.5mph at BPU levels (in summer temperatures). In addition, the entire intake tract is much cooler. The forced convection has almost the effect of a larger intercooler on the intake charge. In fact when the weather is cooler in late fall and early spring the tract leading directly to my stock twins is ice cold to the touch.
