Air is also a LOT thinner. You are at a lot larger risk of KR and fuel system failure than an identical car at an elevation of 1000' as the air at 1000' is quite a bit more dense.
Being cooler may help, but you will still have situations with higher air and engine temps, especially with the smaller pulley and stage II.
I hope your investment works with you and not against you, but you will need exhaust work, fuel system that is up to the task.
You will also have to make sure you get the highest available octane.
I'd suggest you hold off with the chip at least until you have a high flow cat, muffler, and have done a realtime scan with the pulley to verify everything is up to snuff for the chip.
