jetting question for an oldschool Summit x

[Sleddar]

I have a friend that just bought a 1999 Summit X and he is worried that the altitude it is jetted for is too high, he doesn't want to smoke the motor. The guy who sold it to him said it was jetted for 8000ft. most his riding will be done a 5500 -6000. Will he be alright or does he need to rejet? Also is there any charts out there that show the ranges?
Thanks in advance.

Thanks, there is a lot of good info there. The only problem is it doesn't have info for a 1999 sled or a summit.

98 is the same as a 99 the only difference is the needle clip is one step richer than the 98. If He has Dpm and 350 340 mains he should be fine.

Unless someone removed the DPM, the jetting will be the same for any altitude.
