Slicks
13.95 @ 102.3
13.99 @ 102.1

Worn Street Tires
13.56 @ 105.2

Observations
I think I flashed the wrong tune (old one) back when I changed my fan settings before sending my HPTuners to sleepyalero so he can use it for a bit. Sucked not being able to log and investigate exactly what is going on with fueling and spark advance and such down the track. I haven't tuned it since last October, and apparently things changed. I was just able to see a glimpse of the fueling status looking at my gauges periodically down the track.

I suck at launching/turbo lag is bad. Seems to take forever then WHAM power comes on.
ran way richer than it should, and AFR not consistent (10.0 - 11.0).
bounces off rev limiter on the 1-2 shift causing lots of delay.
exhaust cutout is closed.
my tune is made for 100 octane. On 110 my AFR should be like 12.0 or so. tune is also way off.

SUMMARY: Need to retune for either 100 or 110. Preferably dyno tuned, by someone who is better than me. Slicks are not needed it seems. No traction issues.
