The Cobb Stage III tune and sticky (Advan Neova, Direzza Star-spec, etc.) 215/40 tires is the answer. The redline increases to 7000, so (with the slightly taller gearing provided by taller tires) 2nd gear reaches 63 mph, thus elliminating the second shift. Cobb also supplies launch control and flat-foot shifting, and a bunch of extra torque. That's a change of five factors that completely changes your 0-60 times. Flat-foot shifting means the waste gate will not open when you shift, significantly reducing turbo lag entering 2nd gear.
