Walla Walla, WA jetting

Going to the wife's reunion this year, and taking the bikes. Anybody know the jetting for a 2003 WR450F with mods below for about 1500 ft elevation. Somehow I don't think the 8300 ft jetting will work good.

My 450 ran strong at that altitude with a 160 main and a 50 pilot with the standard WR needle in the 4th position.

I am currently running a NCVQ needle 4th position, 162 main, 45 pilot, and a 100 PAJ and the bike rips! Both these are with an uncorked pipe though.
