I would run it for a bit and enjoy it then maybe later you can try a 1500rpm torque spring if you need a little better hill speeds. The 1000rpm does help out , i ran one for about 6months on 5.5g rollers but after trying a 1500rpm i found it suited me better, especially in the 5.1g rollers, my revs now stay up mostly in the 6000-7000rpm range when i ride.
It just takes time, patience and trial and error till you find the best setup that suits you and your terrain.
Its only taken me a year so far of tinkering and testing, but i think im almost at my perfect set up now.......just need the ooen filter dialed in next and that me finished for a while on tuning, it should be at its peak for me then.
