16.155@87.59MPH tonight
No better, and thats after dropping the spare tire, trunk speakers, and tire jack.
However, it was also 10 degrees warmer, and I forgot that I had filled up with 87 octane the week before, so I was only running on 87. My 60's on my best 2 runs were about .1 slower than my best run, so thats where Im gaining the time (or not losing it), but am making up for it in the long accelleration with the weight loss. I'm done beating on the car now until I can afford a chip and intake.

All different kinds, none of them that great, but definitely improving.
At first, I was launching at about 2500 rpm with about 2 seconds of wheelspin in 1st, no bog, and that got me some pretty good results ~16.2
I bogged a couple of launches which really hurt my 60' times, but with the lower weight, my overall times werent that bad ~16.5
After a few runs, I lowered the rear tire pressure to about 23psi from 27 psi. With the lower tire pressure and better traction, I was launching at about 2500 and getting a kind of lurching wheel spin and got my best time of the night, 16.155, then 16.33.
All my trap speeds were pretty consistant around 87.5
