The beauty of that problem, at least in my case, is that the lag is very consistent/repeatable.

You can factor that lag into your shift strategy, and with only a little bit of effort, it will be changing gears when you want.

Just to get slightly off the original topic here.

If you have a G-Tech Pro RR (or whatever they're called) that can be plugged into a PC, do an acceleration run from low RPM to the redline in each gear and graph the acceleration and speed for each gear. Then overlap the 3/4 lines on a single graph, and look where each gear accelerates less than the next gear (IE the lines cross over), that's where the perfect shift point is.

Funny you should say that because I ahve the ss model (same as rr but no download) and its telling me some interesting facts. My peak power rarely hits above 4800rpm.The peak rpm point of a car is dictated mostly by intake and exhaust manifolding.at 4800 rpm peaking power there seems to be something choking airflow and power above this.
