See my Zard thread in performance -> http://www.thespeedtriple.com/Forums/index.php?topic=596.30
The Zard has given me really predictable performance throughout the powerband and more performance up top, but essentially it smoothed everything out while removing some of my low-end grunt at 2-3k. On the plus side, the bike used to be really twitchy and scary to ride with how I've set it up pre-Zard. Now it is cakey scooting around town.
The only thing that bothers me is that I got an earful of data and knowledge from Andy at Metric and learned about how Dynojet essentially adds some calculations to their calculations to bump up the numbers. He said most stock Hayabusas that have come to his dyno have pulled high 130's HP if that is any indication of how fluffy Dynojets are. Anyway, the 'actual' BHP of my bike turned out to be mid to high 90's with torque around the high 50's. The dynojet I had the bike on a few years back said 113hp and 69ft lbs and the bike doesn't feel anywhere NEAR a 20hp power loss, so the 'proof is in the pudding'. I'd like to see a Houston 1050 get on the dyno at Metric and do a few pulls to compare, but overall I'm very pleased with how the bike performs now. I'd just like a lump more power and lower the rear of the bike a bit for better street stability and remove some of the twitchy handling.
