The shift points are easier to manage on the SHO's 6F55 tuning, you really don't need to wind out that motor and stock turbos. I kept mine around 6100 RPM max in the earlier gears. I experimented with the 2-3 and 3-4 at the track to find one that worked better.
I see there might be an aftermarket intercooler option for the SHO which I'd recommend. That being said, the stock intercooler on the SHO seems to be more effective than the stock one on my Fusion Sport.
