I dont know man roughly 60% more power than stock is pretty astronomical especially on only 7 psi. For an example the whipple SC for the 2011 Tang only produces 50% more power on 9.5 psi! Ha i had to, anyway I have the same bike with bmc race ir filter, full titanium exhaust, fully tuned and only putting 110 to the wheel. But could a liter bike hang in the corners?
A 750 could hang in the corners and will produce good power, but unless your really that good of a rider a liter bike is going to easily hang right behind you anyway.
Most street riders do not push the bike anywhere near their handling limits; even if the rider on the 600 was that much better and the liter bike did fall back a little in the turns hes gonna run by u real quick on the first straight away.
Im just saying I don't see the point in boosting a 600... Go for a 750 or a 1000, or a Busa/ZX14 etc...
There are lots of bikes out there that will make that power in N/A trim while not only saving you tons of money will be more reliable as well.
