I checked my compression at home 3500feet above see level and both cylinders (Hot) were 107psi after 5 pulls, does this sound low or is this ok at this elevation?Just curious if i should put a new top end? sled still pulls hard at 2300 miles. Thank any info. would be appreciated.

Make sure you have the throttle wide open during the pulls like M8magic states..
