just looking for some input on what is working is working the best.i just put their kit in a 09 163 ,and it seems to be pulling more top end track speed but up to about 40 mph it seems a little off. i am at lower elevation 3000 ft and less at home.but up to 7000 in the mtns. tried with one 1/4 hex bolt on the end and way to much revs . went to 2, 1/2 hex bolts and one threaded pin,which was about 7800ish ,on clicker #2,and that is what the instuctions call for for rpm. this is in fairly sugary snow. not sure why it is supposed to make more track hp at 7850 vs 8150.but it is not as strong as it was with the stock setup up to 40 mph.track speed going up a modest hill in the loose was about 65 mph.it also lost that surge feeling when the power valves start to open. one thing i did really like was it will hit and stick max rpm, and it seems very smooth. so i guess the ? is where does the weight go to get the best result and how much ?
