Street-tires perform at their optimal level at a given pressure, be it handling or straight-line traction. Dropping the pressure for the drag-strip will only hurt you, if anything at all, although only 2 PSI is not enough to show this.
The laws of lower pressure in drag-tires for proper buckling of the sidewall do not apply for 19", low-profile radials. You will alter the contact-patch upon launch. Google will find you a ton of information on this.

"Traction issue" aside, it still only went 100 MPH. Your MPH will tell you how fast the car is regardless of how it hooks. Still, even if it was spinning half-way down the track, it should have ran quicker.
Supercharged 350Zs have been failing to impress.
