First time at the track with my 2011 wrx stock, second time ever for being at the track. Ill post slip when I can but here's a video. I think I can get quicker than a 14.202 considering my trap speed of 97.87mph @2200ft above sea level.
How did you launch your car? Your time slip looks much like my best run, except I had a stage 1 flash and I was at a lower elevation
I found that launching at 5K got me my best time (the rest were like 3.5K-4K RPM launches). I find that I'm a slow shifter so maybe trying to shift faster might also improve your times.
