Does this sound right? ( 5K' plus jetting )

New to the forum, not new to the KDX... in fact this is a bike ( 95 ) my wife bought me new as a hold over for my B-day in 96. Loved the bike for 4-5 years then had to be sold to pay the bills. Long story short it has been with her brother who never really rode the bike till this fathers day my wife surpised me with the bike.
Now the trouble is the bike was set up for sea level, now I live a 5,400 ft ( Central Idaho ) and ride up from there. The bike runs good but lacks punch and was not idling when warm. I backed the air screw out to about 3.5 turns, opened up the air box a bit and added some idle screw and it just stays idling.
I used candian daves jetting guide and went on the safe side ( I thought ) and ordered a 148, 145 main and 42 pilot. Tonight I pulled the stock jets and they are 48 and 160, seems to be a big jump.
Did I go to low? Any input on those of you running around near 6K would be great... bike is stock motor, slightly opened air box, FMF turbine core silencer, stock pipe. I run 40 to 1 with synthetic and non-ethonal 91.
Got a couple fresh plugs to do some plug chops but would hate to squeck the top end on the ride out.
