There is not much you can do really unless you want to change the IP. The engine will lack some power and smoke a but more. The worst performances come around 10,000', where your going 5000' is really not too bad. If you will be just going over high terrain, I usually just gear down and keep the revs up a bit. If you put your foot into it without gearing down you will see smoke thicker than you've seen before probably. If you have an automatic then the BARO will change the shift to be slightly harder so there is no slipping.

not much you really can do like plc said. higher in alt the less air you get see level the is 14 and like at 8000 feet you go like 8 psi or something like that so you loose alot of air going into the cylinders. only realy way to compensate is to have a turbo, super charger. thus cramming more air into cylinders.

With the turbo you should have no problems at all with the power dropping off.
You will blow slightly more smoke taking off from a stop and the pyrometer may run a little higher than normal.
You should still be able to build the same boost you see at 500 feet.
Watch the tranny and coolant temps, the thinner air will not cool the radiators as well as the air you are used to. The winter season will be working to your advantage though.

With a non turbo you have to worry about overheating the pistons, and wasting fuel. Just watch the black smoke and if it starts to pour out, back out of the throttle some.
Turbos are mostly self-compensating but just the same you should always keep an eye to the tailpipe.
