FW28z - our "toad" is a Can AM Spyder RT. The engine is a de-tuned Aprilia v-twin sport-bike motor. Cruise is 5000 RPM, power peak at 6000 or so and tops out between 9000 and 10000. We can hit 60 mph in first gear - which is kind of a rush when you finally hit the power peak. But, as you said, it took some getting used to!
I'm learning to not react to the V10's screaming although I do try to anticipate the downshifts when I have the cruise control engaged at higher speeds (most of the time) and keep the RPMs under 4000.
As for the 5-Star tune - everything I hear about it is good, but I think I'll wait until I'm near the end of the powertrain warranty before I consider one. 5 Star is quite clear that you should expect the tune to void your warranty.
Besides, I'm actually pretty pleased with the stock performance of the chassis overall.
Regards,
Randy
