Time Slip Comparison ?????
Ok guy's made 2 changes. Went from SS3200 converter to a SS3600 and dropped air pressure from 25lbs hot to 20lbs hot. Temp outside was much warmer last night (I have no idea how to find actual temps for the dates) Best 60' and best ET 
Lost 2+mph 
Here's last time I raced and last nights time slips for comparison. Open to opinions, of which I have recieved a few already.

Here is what I use to find temps & stuff for DA, pretty acurate too!............

Put in your zip and go from there.........
Here are 2 places to .........figure your DA pretty close.

or

Even if its off, its off by the same amount for each day but a good comparison other than a swag

Moroso's Elevation 6'. This is what I got when I plugged in your nbrs using 6:53PM, March 11, 2005.
Density Altitude = 739 feet ET MPH
Uncorrected 12.092 @ 114.85
Corrected 12.00 @ 115.74
For April 28, 2005 at 7:53PM
Density Altitude = 1010 feet ET MPH
Uncorrected 12.068 @ 112.89
Corrected 11.94 @ 114.1
You may want to dbl check this as I did this rather quickly.
The initial results don't have the torque converter change giving you much.

Good runs Bob!! I would raise the pressures back up to about 25. That's where I run and it helps with speed and control going down the track. The M/T's will grip at either pressure, so you will not lose anything off the line. On second thought, try raising the pressure to about 60 psi. I like my position in points, lol.

Was the weather very close for the two races? I know my Vette will loose ET when the hum. is above 65%, Even though the weather station will predict a quicker ET.
Tire pressures sounds a little low.
I think all is in order with your car. I would make more passes to make sure it is consistant.

I'm going to bump the tire pressure back up to 24lbs and see if it still hooks. With the SS3200 converter I had no problem with the ET Streets @ 24-26 lbs. I think the lower pressure in the tires and the warmer temps hurt me a little. Going back this Wednesday to test a little more.
