Make sure you get a good, fresh tank of gas through it. I had the same sled and found that the low end hesitation/bog would clean-up when I ran 89 octane as opposed to 91 octane (I'm in idaho too). The 91 octane was too high for the compression and elevation and did not burn well down low. Also double check power valve synchro and cable tightness...just get both cables to have the same tension. I also found this sled to like more secondary pre-load tension to avoid sluggish or boggy low end.
