I'll give you a hint - with the fuel turned up all the way, on a hard run your EGTs are in the range that will melt your turbo. INSTALL A PYROMETER, then crank the fuel down to a safe level, no more than 1100-1150F on a hard pull unless you want to buy a new turbo. If you can't afford/can't install a pyro, turn down the fuel until you get a light plume of smoke when you upshift and then no more smoke when you get in the 1800-2000 rpm range. Any more fuel than that and you WILL eventually fry your turbo!
Note that EGTs are dependent on ambient temperature. I have noticed my EGTs have dropped 50-100F from summertime to fall temperatures (well maybe winter time temps, we've already had an 8" snowfall out here, night time temps fall to the mid 20s, but REAL wintertime lows are about 0F out here in western Michigan). But I use an electronic pyrometer which corrects EGT based on ambient temps vs a mechanical pryo which assumes an ambient temp of 70F.
