Had a great first day at the dragstrip today at Capitol Raceway in Maryland. I wanted to get some baseline runs before tuning this summer, as well as get some drag experience under my belt. Since it was my first time, I skipped the burnouts for the first 3 runs and tried using Launch Control. I kept slipping and bogging like crazy!! ETs were in the 14's and I was getting frustrated.
So then I changed up my technique. I dropped the rear tire pressure to 31 psi (fronts were kept inflated at 38), did a very quick burnout before staging just to get all the gravel and rocks off the tires, and tried brake torquing myself (to around 2000 rpm after staging). Kept it in Sport+ and shifter in S mode. I didn't care too much about reaction times since I was just doing test and tune. This was much better! I'm quite disappointed in the launch control, but maybe it was just getting a few runs in, maybe it was the quick burnouts, maybe it was the tire pressure, but the next 3 runs were much better in the low-mid 13s. Not too bad considering I see published times higher than that, and I'm still stock other than the wheels/tires (OEM M2 setup).
Here's my last and best run of the day (I'm on the left):
13.270 @ 106.34 mph
How's this look? What can I do to improve my launch and 60' time? I couldn't seem to be able to break under 2.0.
