Just curious, is your car bogging between shifts? Also, from what I've learned with racing other N54's that were AT's and DCT, the only way you will keep up is from 3rd gear 60 roll. The 2-3 shift kills the 6mt no matter how fast you shift. The gear spread is too large, and if you do shift fast you'll just bog.
