Yes, it does. If you don't have your car tuned for the turbo you can run lean. If you run lean, you run hot. Another problem is detonation (due to lean conditions, check your A/F ratio), I have seen some people that recommend retarding your timing to also help the whole lean condition situation. Though not all applications call for this tuning, I have heard of it being a problem. Don't take my word for it (what do I know right?). Check this site out:
