Here are some no-cost things that you can do to increase performance (or at least responsiveness):
Turn off your A/C - Modern compressors sap only a few HP? Maybe, but they decrease throttle response big-time, even when runing a Maggie. With the A/C off, the throttle response goes from 'superb' to 'amazing.'
Run the right tire pressure - 37-40 PSI hot works very well for my 19" PS-2's. I don't know what the difference in rolling resistance is between 35 PSI hot and 38 PSI hot, but our cars are heavy and there's a big reduction in responsiveness at the lower temp. I can feel no reduction in traction. Note: If you live in a '4-season' climate, you'll have to adjust pressures several times a year to make this happen.
Reduce exterior noise in the cockpit - Earplugs are commonly used by motorcyclists, maostly to preserve hearing. However, a lesser-known effect is riding faster! Why? Humans naturally avoid loud noise, even noise that they like (rock music, engines, etc) - esp over longer durations. Humans also tend to perform better in calmer environments. So noise and other 'calamity' often causes an avoidance response, and we come out of the throttle (even if just a bit). I don't wear earplugs in the V, but I have sound-reduced it a bunch with Dynamat Extreme ($$$/weight). But even play jazz loud helps me stay in a lower gear longer (free)....
For many out there, these are 'duh' material. But I hope that they help some folks get more pleasure from these fine machines...at no cost!
Bob Maggie, K&N, Corsa, StealthTune, FG2, Sways, etc.
I've played with the points on the tune, and Stealth's are acutally pretty spot on. I don't recall the on/off points - but they're low enough and done intelligently enough so that part throttle response...well...in response to the M boys, I call it V mode
