Im comparing my time slips and wondering where I'm possibly losing time. Could be my wheel set up, tune, etc?

1st Slip 9/13/2012: Vararam, Cortex93, 75% trans, Shift points raised 200, Stock 19s on Crapyears
60' - 2.068
330 - 5.692
1/8 - 8.633 @ 83.15
1000 11.16
E.T. - 13.291 @ 105.52
(This was my only day at the track with Cortex)

2nd + 3rd Slip 2/23/2013: Vararam, SLP LTs with 20s on Bridgestone RE960 349rwhp/359tq custom tune
2nd Slip
60' - 2.036
330 - 5.599
1/8 - 8.541 @ 84.11
1000 - 11.048
E.T - 13.163 @ 105.55

3rd (50min after 2nd slip)
60' - 2.001
330 - 5.592
1/8 - 8.548 @ 83.96
1000 - 11.072
E.T. - 13.197 @ 105.26

I guess my first question is should my times between the run with cortex and the run with LTs be that close? And my second question is, shouldn't my 3rd slip time be quicker than time slip 2? Somewhere between my 60' and the 1/8 on the 3rd slip I lost time. Would that be tune issue or what?

Each of the 3 runs were done in sport mode. When the light turns green I gun it. I tried the other launch techniques but this yields the best times for me.

I ran a 13.4 @106 mph at the trap. I had it in sports mode, however it did bogg before it trapped. I think next time I'm going to stick it in manual mode and give that a shot. I have a cortex tune and vararam intake. Just recently purchased kooks lt and corsa catback. Gotta wait to put those on while I'm fighting with the crappy dealership.

Do you hold third before the trap? I did and got a 13 flat pass. Forget the mph atm. I have a rotofab, tune, trans tune, xpipe and stall converter. I'm very close to the ocean tho and it was late in the season so the air was cold and humidity was low.

what time of the day for each pass? The weather and Density Altitude play a big role in your times
The run in Sept the temp was 79 and the DA was 1607. Corrected ET 13.053 @ 107.483. The 2nd n 3rd run in Feb this year, the temps were 48.9/DA(-347) and 50/DA(-260) respectively. Corrected time for 2nd (13.183 @ 105.440) and 3rd (13.202 @ 105.287). Hmm, I guess I was supposed to run slower?

I didn't hold 3rd. I know it shifts into 4th just before the line. Our track elevation is 273.

1st slip I was on street tires Goodyear all season's with stock 19s. 2nd n 3rd was in Bridgestones RE960 all seasons. I know radials will help my timing. Technically speaking shouldn't my third run be quicker than my second run? I know with my 20s my time is going to be slower. Right now in trying to figure out with a quicker 60', why would my time/speed be slower.
