If your cooling system is operating correctly, the temp gauge should be pretty well dead-center. 190-205˚ isn't out of line for pulling up a hill or hard acceleration. If the temp comes right back down, it isn't an item to worry about. Check your boost pressure. If the turbo is making low boost, you'll be running high EGT's.
