Most use a one foot roll out which will give you a better time. There was some wheel spin to. With the 1 ft roll out, you might have hit 3.9. The 1/4 mile at 12.2 @ 118 mph is pretty awesome and probably bang on if you take into account not using the roll out and the 2 meters more needed for a 1/4 mile. I think with less wheel spin an 11.9 is doable.

You can also play around with short shifting at about 6200 after 2nd gear as others have recommended.

You're a champ. Thanks!!!
