hello i just bout a used m1100t and want to do some clutching. the sled has a straight pipe,boost tubes and a CE. i live at 1500 feet of elevation and that is were id most of my riding. but i make some trips to the mountains so i would like have it fine tuned at 1500 and pretty good in the mountains. what do you guys recomend? maybe a shockwave helix? i am bouncing of the rev limiter with stock weight so i will need something heavier.
